```
A date-time with an offset from UTC/Greenwich in the ISO-8601 calendar system, such as 2007-12-03T10:15:30+01:00.
OffsetDateTime is an immutable representation of a date-time with an offset. This class stores all date and time fields, to a precision of nanoseconds, as well as the offset from UTC/Greenwich. For example, the value "2nd October 2007 at 13:45.30.123456789 +02:00" can be stored in an OffsetDateTime.
OffsetDateTime, ZonedDateTime and Instant all store an instant on the time-line to nanosecond precision. Instant is the simplest, simply representing the instant. OffsetDateTime adds to the instant the offset from UTC/Greenwich, which allows the local date-time to be obtained. ZonedDateTime adds full time-zone rules.
It is intended that ZonedDateTime or Instant is used to model data in simpler applications. This class may be used when modeling date-time concepts in more detail, or when communicating to a database or in a network protocol.
This is a value-based class; use of identity-sensitive operations (including reference equality (==), identity hash code, or synchronization) on instances of OffsetDateTime may have unpredictable results and should be avoided. The equals method should be used for comparisons.

```
public static final OffsetDateTime MAX
```
    The maximum supported OffsetDateTime, '+999999999-12-31T23:59:59.999999999-18:00'. This is the local date-time just before midnight at the end of the maximum date in the minimum offset (larger negative offsets are later on the time-line). This combines LocalDateTime#MAX and ZoneOffset#MIN. This could be used by an application as a "far future" date-time.
  - MIN
```
public static final OffsetDateTime MIN
```
    The minimum supported OffsetDateTime, '-999999999-01-01T00:00:00+18:00'. This is the local date-time of midnight at the start of the minimum date in the maximum offset (larger offsets are earlier on the time-line). This combines LocalDateTime#MIN and ZoneOffset#MAX. This could be used by an application as a "far past" date-time.

  - now
```
public static OffsetDateTime now()
```
    Obtains the current date-time from the system clock in the default time-zone.
    This will query the Clock#systemDefaultZone() in the default time-zone to obtain the current date-time. The offset will be calculated from the time-zone in the clock.
    Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.

  - now
```
public static OffsetDateTime now(ZoneId zone)
```
    Obtains the current date-time from the system clock in the specified time-zone.
    This will query the Clock#system(ZoneId) to obtain the current date-time. Specifying the time-zone avoids dependence on the default time-zone. The offset will be calculated from the specified time-zone.
    Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.

```
    Obtains an instance of OffsetDateTime from a year, month, day, hour, minute, second, nanosecond and offset.
    This creates an offset date-time with the seven specified fields.
    This method exists primarily for writing test cases. Non test-code will typically use other methods to create an offset time. LocalDateTime has five additional convenience variants of the equivalent factory method taking fewer arguments. They are not provided here to reduce the footprint of the API.
    
    参数:
    
    year - the year to represent, from MIN_YEAR to MAX_YEAR
    
    month - the month-of-year to represent, from 1 (January) to 12 (December)
    
    dayOfMonth - the day-of-month to represent, from 1 to 31
    
    hour - the hour-of-day to represent, from 0 to 23

public static OffsetDateTime ofInstant(Instant instant,
                                       ZoneId zone)
```
    Obtains an instance of OffsetDateTime from an Instant and zone ID.
    This creates an offset date-time with the same instant as that specified. Finding the offset from UTC/Greenwich is simple as there is only one valid offset for each instant.
    
    参数:
    
    instant - the instant to create the date-time from, not null
    
    zone - the time-zone, which may be an offset, not null
    
    返回:
    
    the offset date-time, not null
    
    抛出:
    
    DateTimeException - if the result exceeds the supported range
  - from
```
public static OffsetDateTime from(TemporalAccessor temporal)
```
    Obtains an instance of OffsetDateTime from a temporal object.
    This obtains an offset date-time based on the specified temporal. A TemporalAccessor represents an arbitrary set of date and time information, which this factory converts to an instance of OffsetDateTime.
    The conversion will first obtain a ZoneOffset from the temporal object. It will then try to obtain a LocalDateTime, falling back to an Instant if necessary. The result will be the combination of ZoneOffset with either with LocalDateTime or Instant. Implementations are permitted to perform optimizations such as accessing those fields that are equivalent to the relevant objects.
    This method matches the signature of the functional interface TemporalQuery allowing it to be used as a query via method reference, OffsetDateTime::from.
    
    参数:
    
    temporal - the temporal object to convert, not null
    
    返回:
    
    the offset date-time, not null
    
    抛出:
    
    DateTimeException - if unable to convert to an OffsetDateTime
  - parse
```
public static OffsetDateTime parse(CharSequence text)
```
    Obtains an instance of OffsetDateTime from a text string such as 2007-12-03T10:15:30+01:00.
    The string must represent a valid date-time and is parsed using DateTimeFormatter.ISO_OFFSET_DATE_TIME.
    
    参数:
    
    text - the text to parse such as "2007-12-03T10:15:30+01:00", not null
    
    返回:
    
    the parsed offset date-time, not null

    抛出:
    
    DateTimeParseException - if the text cannot be parsed
  - isSupported
```
public boolean isSupported(TemporalField field)
```
    Checks if the specified field is supported.
    This checks if this date-time can be queried for the specified field. If false, then calling the range, get and with(java.time.temporal.TemporalField,long) methods will throw an exception.
    If the field is a ChronoField then the query is implemented here. The supported fields are:
    - NANO_OF_SECOND
    - NANO_OF_DAY
    - MICRO_OF_SECOND
    - MICRO_OF_DAY

    - OFFSET_SECONDS
    All other ChronoField instances will return false.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor) passing this as the argument. Whether the field is supported is determined by the field.
    指定者:

    true if the field is supported on this date-time, false if not
  - isSupported
```
public boolean isSupported(TemporalUnit unit)
```
    Checks if the specified unit is supported.
    This checks if the specified unit can be added to, or subtracted from, this date-time. If false, then calling the plus(long,java.time.temporal.TemporalUnit) and minus methods will throw an exception.
    If the unit is a ChronoUnit then the query is implemented here. The supported units are:
    - NANOS
    - MICROS
    - MILLIS
    - SECONDS
    - MINUTES
    - HOURS
    - HALF_DAYS
    - DAYS

    - YEARS
    - DECADES
    - CENTURIES
    - MILLENNIA
    - ERAS
    All other ChronoUnit instances will return false.
    If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.isSupportedBy(Temporal) passing this as the argument. Whether the unit is supported is determined by the unit.
    指定者:
    
    isSupported 在接口中 Temporal
    
    参数:
    
    unit - the unit to check, null returns false

    true if the unit can be added/subtracted, false if not
  - range
```
public ValueRange range(TemporalField field)
```
    Gets the range of valid values for the specified field.
    The range object expresses the minimum and maximum valid values for a field. This date-time is used to enhance the accuracy of the returned range. If it is not possible to return the range, because the field is not supported or for some other reason, an exception is thrown.
    If the field is a ChronoField then the query is implemented here. The supported fields will return appropriate range instances. All other ChronoField instances will throw an UnsupportedTemporalTypeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.rangeRefinedBy(TemporalAccessor) passing this as the argument. Whether the range can be obtained is determined by the field.
    
    指定者:
    
    range 在接口中 TemporalAccessor
    
    参数:
    
    field - the field to query the range for, not null
    
    返回:
    
    the range of valid values for the field, not null
    
    抛出:
    
    DateTimeException - if the range for the field cannot be obtained
    
    UnsupportedTemporalTypeException - if the field is not supported
  - get
```
public int get(TemporalField field)
```
    Gets the value of the specified field from this date-time as an int.
    This queries this date-time for the value of the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.
    If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this date-time, except NANO_OF_DAY, MICRO_OF_DAY, EPOCH_DAY, PROLEPTIC_MONTH and INSTANT_SECONDS which are too large to fit in an int and throw a DateTimeException. All other ChronoField instances will throw an UnsupportedTemporalTypeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.
    
    指定者:

  - getOffset
```
public ZoneOffset getOffset()
```
    Gets the zone offset, such as '+01:00'.
    This is the offset of the local date-time from UTC/Greenwich.
    
    返回:
    
    the zone offset, not null
  - withOffsetSameLocal
```
public OffsetDateTime withOffsetSameLocal(ZoneOffset offset)
```
    Returns a copy of this OffsetDateTime with the specified offset ensuring that the result has the same local date-time.
    This method returns an object with the same LocalDateTime and the specified ZoneOffset. No calculation is needed or performed. For example, if this time represents 2007-12-03T10:30+02:00 and the offset specified is +03:00, then this method will return 2007-12-03T10:30+03:00.
    To take into account the difference between the offsets, and adjust the time fields, use withOffsetSameInstant(java.time.ZoneOffset).
    This instance is immutable and unaffected by this method call.
    
    参数:
    
    offset - the zone offset to change to, not null
    
    返回:
    
    an OffsetDateTime based on this date-time with the requested offset, not null
  - withOffsetSameInstant
```
public OffsetDateTime withOffsetSameInstant(ZoneOffset offset)
```
    Returns a copy of this OffsetDateTime with the specified offset ensuring that the result is at the same instant.
    This method returns an object with the specified ZoneOffset and a LocalDateTime adjusted by the difference between the two offsets. This will result in the old and new objects representing the same instant. This is useful for finding the local time in a different offset. For example, if this time represents 2007-12-03T10:30+02:00 and the offset specified is +03:00, then this method will return 2007-12-03T11:30+03:00.
    To change the offset without adjusting the local time use withOffsetSameLocal(java.time.ZoneOffset).
    This instance is immutable and unaffected by this method call.

public Month getMonth()
```
    Gets the month-of-year field using the Month enum.
    This method returns the enum Month for the month. This avoids confusion as to what int values mean. If you need access to the primitive int value then the enum provides the Month#getValue().
    
    返回:
    
    the month-of-year, not null
    
    另请参阅:

```
public DayOfWeek getDayOfWeek()
```
    Gets the day-of-week field, which is an enum DayOfWeek.
    This method returns the enum DayOfWeek for the day-of-week. This avoids confusion as to what int values mean. If you need access to the primitive int value then the enum provides the DayOfWeek#getValue().
    Additional information can be obtained from the DayOfWeek. This includes textual names of the values.
    
    返回:
    
    the day-of-week, not null
  - toLocalTime

    the nano-of-second, from 0 to 999,999,999
  - with
```
public OffsetDateTime with(TemporalAdjuster adjuster)
```
    Returns an adjusted copy of this date-time.
    This returns an OffsetDateTime, based on this one, with the date-time adjusted. The adjustment takes place using the specified adjuster strategy object. Read the documentation of the adjuster to understand what adjustment will be made.
    A simple adjuster might simply set the one of the fields, such as the year field. A more complex adjuster might set the date to the last day of the month. A selection of common adjustments is provided in TemporalAdjusters. These include finding the "last day of the month" and "next Wednesday". Key date-time classes also implement the TemporalAdjuster interface, such as Month and MonthDay. The adjuster is responsible for handling special cases, such as the varying lengths of month and leap years.
    For example this code returns a date on the last day of July:
```
  import static java.time.Month.*;
  import static java.time.temporal.TemporalAdjusters.*;

  result = offsetDateTime.with(JULY).with(lastDayOfMonth());
 
```
    The classes LocalDate, LocalTime and ZoneOffset implement TemporalAdjuster, thus this method can be used to change the date, time or offset:
```
  result = offsetDateTime.with(date);
  result = offsetDateTime.with(time);
  result = offsetDateTime.with(offset);
 
```
    The result of this method is obtained by invoking the TemporalAdjuster#adjustInto(Temporal) method on the specified adjuster passing this as the argument.
    This instance is immutable and unaffected by this method call.
    指定者:
    
    with 在接口中 Temporal
    
    参数:
    
    adjuster - the adjuster to use, not null
    
    返回:
    
    an OffsetDateTime based on this with the adjustment made, not null
    
    抛出:
    
    DateTimeException - if the adjustment cannot be made
    
    ArithmeticException - if numeric overflow occurs
  - with
```
public OffsetDateTime with(TemporalField field,
                           long newValue)
```
    Returns a copy of this date-time with the specified field set to a new value.
    This returns an OffsetDateTime, based on this one, with the value for the specified field changed. This can be used to change any supported field, such as the year, month or day-of-month. If it is not possible to set the value, because the field is not supported or for some other reason, an exception is thrown.
    In some cases, changing the specified field can cause the resulting date-time to become invalid, such as changing the month from 31st January to February would make the day-of-month invalid. In cases like this, the field is responsible for resolving the date. Typically it will choose the previous valid date, which would be the last valid day of February in this example.
    If the field is a ChronoField then the adjustment is implemented here.
    The INSTANT_SECONDS field will return a date-time with the specified instant. The offset and nano-of-second are unchanged. If the new instant value is outside the valid range then a DateTimeException will be thrown.
    The OFFSET_SECONDS field will return a date-time with the specified offset. The local date-time is unaltered. If the new offset value is outside the valid range then a DateTimeException will be thrown.
    The other supported fields will behave as per the matching method on LocalDateTime#with(TemporalField, long). In this case, the offset is not part of the calculation and will be unchanged.
    All other ChronoField instances will throw an UnsupportedTemporalTypeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.adjustInto(Temporal, long) passing this as the argument. In this case, the field determines whether and how to adjust the instant.
    This instance is immutable and unaffected by this method call.

public OffsetDateTime truncatedTo(TemporalUnit unit)
```
    Returns a copy of this OffsetDateTime with the time truncated.
    Truncation returns a copy of the original date-time with fields smaller than the specified unit set to zero. For example, truncating with the ChronoUnit#MINUTES unit will set the second-of-minute and nano-of-second field to zero.
    The unit must have a TemporalUnit#getDuration() that divides into the length of a standard day without remainder. This includes all supplied time units on ChronoUnit and ChronoUnit#DAYS. Other units throw an exception.
    The offset does not affect the calculation and will be the same in the result.

  - plus
```
public OffsetDateTime plus(TemporalAmount amountToAdd)
```
    Returns a copy of this date-time with the specified amount added.
    This returns an OffsetDateTime, based on this one, with the specified amount added. The amount is typically Period or Duration but may be any other type implementing the TemporalAmount interface.
    The calculation is delegated to the amount object by calling TemporalAmount#addTo(Temporal). The amount implementation is free to implement the addition in any way it wishes, however it typically calls back to plus(long,java.time.temporal.TemporalUnit). Consult the documentation of the amount implementation to determine if it can be successfully added.
    This instance is immutable and unaffected by this method call.

```
    Returns a copy of this date-time with the specified amount added.
    This returns an OffsetDateTime, based on this one, with the amount in terms of the unit added. If it is not possible to add the amount, because the unit is not supported or for some other reason, an exception is thrown.
    If the field is a ChronoUnit then the addition is implemented by LocalDateTime#plus(long, TemporalUnit). The offset is not part of the calculation and will be unchanged in the result.
    If the field is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.addTo(Temporal, long) passing this as the argument. In this case, the unit determines whether and how to perform the addition.

  - plusYears
```
public OffsetDateTime plusYears(long years)
```
    Returns a copy of this OffsetDateTime with the specified number of years added.
    This method adds the specified amount to the years field in three steps:
    1. Add the input years to the year field
    2. Check if the resulting date would be invalid
    3. Adjust the day-of-month to the last valid day if necessary
    For example, 2008-02-29 (leap year) plus one year would result in the invalid date 2009-02-29 (standard year). Instead of returning an invalid result, the last valid day of the month, 2009-02-28, is selected instead.
    This instance is immutable and unaffected by this method call.

    Returns a copy of this OffsetDateTime with the specified number of months added.
    This method adds the specified amount to the months field in three steps:
    1. Add the input months to the month-of-year field
    2. Check if the resulting date would be invalid
    3. Adjust the day-of-month to the last valid day if necessary
    For example, 2007-03-31 plus one month would result in the invalid date 2007-04-31. Instead of returning an invalid result, the last valid day of the month, 2007-04-30, is selected instead.

public OffsetDateTime plusWeeks(long weeks)
```
    Returns a copy of this OffsetDateTime with the specified number of weeks added.
    This method adds the specified amount in weeks to the days field incrementing the month and year fields as necessary to ensure the result remains valid. The result is only invalid if the maximum/minimum year is exceeded.
    For example, 2008-12-31 plus one week would result in 2009-01-07.

    This returns an OffsetDateTime, based on this one, with the specified amount subtracted. The amount is typically Period or Duration but may be any other type implementing the TemporalAmount interface.
    The calculation is delegated to the amount object by calling TemporalAmount#subtractFrom(Temporal). The amount implementation is free to implement the subtraction in any way it wishes, however it typically calls back to minus(long,java.time.temporal.TemporalUnit). Consult the documentation of the amount implementation to determine if it can be successfully subtracted.
    This instance is immutable and unaffected by this method call.

public OffsetDateTime minus(long amountToSubtract,
                            TemporalUnit unit)
```
    Returns a copy of this date-time with the specified amount subtracted.
    This returns an OffsetDateTime, based on this one, with the amount in terms of the unit subtracted. If it is not possible to subtract the amount, because the unit is not supported or for some other reason, an exception is thrown.
    This method is equivalent to plus(long,java.time.temporal.TemporalUnit) with the amount negated. See that method for a full description of how addition, and thus subtraction, works.
    This instance is immutable and unaffected by this method call.

  - minusYears
```
public OffsetDateTime minusYears(long years)
```
    Returns a copy of this OffsetDateTime with the specified number of years subtracted.
    This method subtracts the specified amount from the years field in three steps:
    1. Subtract the input years from the year field
    2. Check if the resulting date would be invalid
    3. Adjust the day-of-month to the last valid day if necessary
    For example, 2008-02-29 (leap year) minus one year would result in the invalid date 2009-02-29 (standard year). Instead of returning an invalid result, the last valid day of the month, 2009-02-28, is selected instead.
    This instance is immutable and unaffected by this method call.
    参数:
    
    years - the years to subtract, may be negative
    
    返回:
    
    an OffsetDateTime based on this date-time with the years subtracted, not null
    
    抛出:

  - minusMonths
```
public OffsetDateTime minusMonths(long months)
```
    Returns a copy of this OffsetDateTime with the specified number of months subtracted.
    This method subtracts the specified amount from the months field in three steps:
    1. Subtract the input months from the month-of-year field
    2. Check if the resulting date would be invalid
    3. Adjust the day-of-month to the last valid day if necessary
    For example, 2007-03-31 minus one month would result in the invalid date 2007-04-31. Instead of returning an invalid result, the last valid day of the month, 2007-04-30, is selected instead.
    This instance is immutable and unaffected by this method call.
    参数:
    
    months - the months to subtract, may be negative
    
    返回:
    
    an OffsetDateTime based on this date-time with the months subtracted, not null
    
    抛出:
    
    DateTimeException - if the result exceeds the supported date range
  - minusWeeks
```
public OffsetDateTime minusWeeks(long weeks)
```
    Returns a copy of this OffsetDateTime with the specified number of weeks subtracted.
    This method subtracts the specified amount in weeks from the days field decrementing the month and year fields as necessary to ensure the result remains valid. The result is only invalid if the maximum/minimum year is exceeded.
    For example, 2008-12-31 minus one week would result in 2009-01-07.
    This instance is immutable and unaffected by this method call.
    
    参数:
    
    weeks - the weeks to subtract, may be negative

public OffsetDateTime minusNanos(long nanos)
```
    Returns a copy of this OffsetDateTime with the specified number of nanoseconds subtracted.
    This instance is immutable and unaffected by this method call.
    
    参数:
    
    nanos - the nanos to subtract, may be negative
    
    返回:
    
    an OffsetDateTime based on this date-time with the nanoseconds subtracted, not null
    
    抛出:
    
    DateTimeException - if the result exceeds the supported date range
  - query
```
public <R> R query(TemporalQuery<R> query)
```
    Queries this date-time using the specified query.
    This queries this date-time using the specified query strategy object. The TemporalQuery object defines the logic to be used to obtain the result. Read the documentation of the query to understand what the result of this method will be.
    The result of this method is obtained by invoking the TemporalQuery#queryFrom(TemporalAccessor) method on the specified query passing this as the argument.
    
    指定者:
    
    query 在接口中 TemporalAccessor
    
    类型参数:
    
    R - the type of the result
    
    参数:
    
    query - the query to invoke, not null
    
    返回:
    
    the query result, null may be returned (defined by the query)
    
    抛出:
    
    DateTimeException - if unable to query (defined by the query)
    
    ArithmeticException - if numeric overflow occurs (defined by the query)
  - adjustInto
```
public Temporal adjustInto(Temporal temporal)
```
    Adjusts the specified temporal object to have the same offset, date and time as this object.
    This returns a temporal object of the same observable type as the input with the offset, date and time changed to be the same as this.
    The adjustment is equivalent to using Temporal#with(TemporalField, long) three times, passing ChronoField#EPOCH_DAY, ChronoField#NANO_OF_DAY and ChronoField#OFFSET_SECONDS as the fields.
    In most cases, it is clearer to reverse the calling pattern by using Temporal#with(TemporalAdjuster):
```
   // these two lines are equivalent, but the second approach is recommended
   temporal = thisOffsetDateTime.adjustInto(temporal);
   temporal = temporal.with(thisOffsetDateTime);
 
```
    This instance is immutable and unaffected by this method call.
    指定者:
    
    adjustInto 在接口中 TemporalAdjuster
    
    参数:
    
    temporal - the target object to be adjusted, not null
    
    返回:
    
    the adjusted object, not null
    
    抛出:
    
    DateTimeException - if unable to make the adjustment
    
    ArithmeticException - if numeric overflow occurs
  - until
```
public long until(Temporal endExclusive,
                  TemporalUnit unit)
```
    Calculates the amount of time until another date-time in terms of the specified unit.
    This calculates the amount of time between two OffsetDateTime objects in terms of a single TemporalUnit. The start and end points are this and the specified date-time. The result will be negative if the end is before the start. For example, the amount in days between two date-times can be calculated using startDateTime.until(endDateTime, DAYS).
    The Temporal passed to this method is converted to a OffsetDateTime using from(java.time.temporal.TemporalAccessor). If the offset differs between the two date-times, the specified end date-time is normalized to have the same offset as this date-time.
    The calculation returns a whole number, representing the number of complete units between the two date-times. For example, the amount in months between 2012-06-15T00:00Z and 2012-08-14T23:59Z will only be one month as it is one minute short of two months.
    There are two equivalent ways of using this method. The first is to invoke this method. The second is to use TemporalUnit#between(Temporal, Temporal):
```
   // these two lines are equivalent
   amount = start.until(end, MONTHS);
   amount = MONTHS.between(start, end);
 
```
    The choice should be made based on which makes the code more readable.
    The calculation is implemented in this method for ChronoUnit. The units NANOS, MICROS, MILLIS, SECONDS, MINUTES, HOURS and HALF_DAYS, DAYS, WEEKS, MONTHS, YEARS, DECADES, CENTURIES, MILLENNIA and ERAS are supported. Other ChronoUnit values will throw an exception.
    If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.between(Temporal, Temporal) passing this as the first argument and the converted input temporal as the second argument.
    This instance is immutable and unaffected by this method call.
    指定者:
    
    until 在接口中 Temporal
    
    参数:
    
    endExclusive - the end date, exclusive, which is converted to an OffsetDateTime, not null
    
    unit - the unit to measure the amount in, not null
    
    返回:
    
    the amount of time between this date-time and the end date-time
    
    抛出:
    
    DateTimeException - if the amount cannot be calculated, or the end temporal cannot be converted to an OffsetDateTime
    
    UnsupportedTemporalTypeException - if the unit is not supported
    
    ArithmeticException - if numeric overflow occurs
  - format
```
public String format(DateTimeFormatter formatter)
```
    Formats this date-time using the specified formatter.
    This date-time will be passed to the formatter to produce a string.
    
    参数:
    
    formatter - the formatter to use, not null
    
    返回:
    
    the formatted date-time string, not null
    
    抛出:
    
    DateTimeException - if an error occurs during printing
  - atZoneSameInstant
```
public ZonedDateTime atZoneSameInstant(ZoneId zone)
```
    Combines this date-time with a time-zone to create a ZonedDateTime ensuring that the result has the same instant.
    This returns a ZonedDateTime formed from this date-time and the specified time-zone. This conversion will ignore the visible local date-time and use the underlying instant instead. This avoids any problems with local time-line gaps or overlaps. The result might have different values for fields such as hour, minute an even day.
    To attempt to retain the values of the fields, use atZoneSimilarLocal(java.time.ZoneId). To use the offset as the zone ID, use toZonedDateTime().
    
    参数:
    
    zone - the time-zone to use, not null
    
    返回:
    
    the zoned date-time formed from this date-time, not null
  - atZoneSimilarLocal
```
public ZonedDateTime atZoneSimilarLocal(ZoneId zone)
```
    Combines this date-time with a time-zone to create a ZonedDateTime trying to keep the same local date and time.
    This returns a ZonedDateTime formed from this date-time and the specified time-zone. Where possible, the result will have the same local date-time as this object.
    Time-zone rules, such as daylight savings, mean that not every time on the local time-line exists. If the local date-time is in a gap or overlap according to the rules then a resolver is used to determine the resultant local time and offset. This method uses ZonedDateTime#ofLocal(LocalDateTime, ZoneId, ZoneOffset) to retain the offset from this instance if possible.
    Finer control over gaps and overlaps is available in two ways. If you simply want to use the later offset at overlaps then call ZonedDateTime#withLaterOffsetAtOverlap() immediately after this method.
    To create a zoned date-time at the same instant irrespective of the local time-line, use atZoneSameInstant(java.time.ZoneId). To use the offset as the zone ID, use toZonedDateTime().
    
    参数:
    
    zone - the time-zone to use, not null
    
    返回:
    
    the zoned date-time formed from this date and the earliest valid time for the zone, not null
  - toOffsetTime
```
public OffsetTime toOffsetTime()
```
    Converts this date-time to an OffsetTime.
    This returns an offset time with the same local time and offset.
    
    返回:
    
    an OffsetTime representing the time and offset, not null
  - toZonedDateTime
```
public ZonedDateTime toZonedDateTime()
```
    Converts this date-time to a ZonedDateTime using the offset as the zone ID.
    This creates the simplest possible ZonedDateTime using the offset as the zone ID.
    To control the time-zone used, see atZoneSameInstant(java.time.ZoneId) and atZoneSimilarLocal(java.time.ZoneId).
    
    返回:
    
    a zoned date-time representing the same local date-time and offset, not null
  - toInstant
```
public Instant toInstant()
```
    Converts this date-time to an Instant.
    This returns an Instant representing the same point on the time-line as this date-time.
    
    返回:
    
    an Instant representing the same instant, not null
  - toEpochSecond
```
public long toEpochSecond()
```
    Converts this date-time to the number of seconds from the epoch of 1970-01-01T00:00:00Z.
    This allows this date-time to be converted to a value of the ChronoField#INSTANT_SECONDS field. This is primarily intended for low-level conversions rather than general application usage.
    
    返回:
    
    the number of seconds from the epoch of 1970-01-01T00:00:00Z
  - compareTo
```
public int compareTo(OffsetDateTime other)
```
    Compares this date-time to another date-time.
    The comparison is based on the instant then on the local date-time. It is "consistent with equals", as defined by Comparable.
    For example, the following is the comparator order:
    1. 2008-12-03T10:30+01:00
    2. 2008-12-03T11:00+01:00
    3. 2008-12-03T12:00+02:00
    4. 2008-12-03T11:30+01:00
    5. 2008-12-03T12:00+01:00
    6. 2008-12-03T12:30+01:00
    Values #2 and #3 represent the same instant on the time-line. When two values represent the same instant, the local date-time is compared to distinguish them. This step is needed to make the ordering consistent with equals().
    指定者:
    
    compareTo 在接口中 Comparable<OffsetDateTime>
    
    参数:
    
    other - the other date-time to compare to, not null
    
    返回:
    
    the comparator value, negative if less, positive if greater
  - isAfter
```
public boolean isAfter(OffsetDateTime other)
```
    Checks if the instant of this date-time is after that of the specified date-time.
    This method differs from the comparison in compareTo(java.time.OffsetDateTime) and equals(java.lang.Object) in that it only compares the instant of the date-time. This is equivalent to using dateTime1.toInstant().isAfter(dateTime2.toInstant());.
    
    参数:
    
    other - the other date-time to compare to, not null
    
    返回:
    
    true if this is after the instant of the specified date-time
  - isBefore
```
public boolean isBefore(OffsetDateTime other)
```
    Checks if the instant of this date-time is before that of the specified date-time.
    This method differs from the comparison in compareTo(java.time.OffsetDateTime) in that it only compares the instant of the date-time. This is equivalent to using dateTime1.toInstant().isBefore(dateTime2.toInstant());.
    
    参数:
    
    other - the other date-time to compare to, not null
    
    返回:
    
    true if this is before the instant of the specified date-time
  - isEqual
```
public boolean isEqual(OffsetDateTime other)
```
    Checks if the instant of this date-time is equal to that of the specified date-time.
    This method differs from the comparison in compareTo(java.time.OffsetDateTime) and equals(java.lang.Object) in that it only compares the instant of the date-time. This is equivalent to using dateTime1.toInstant().equals(dateTime2.toInstant());.
    
    参数:
    
    other - the other date-time to compare to, not null
    
    返回:
    
    true if the instant equals the instant of the specified date-time
  - equals
```
public boolean equals(Object obj)
```
    Checks if this date-time is equal to another date-time.
    The comparison is based on the local date-time and the offset. To compare for the same instant on the time-line, use isEqual(java.time.OffsetDateTime). Only objects of type OffsetDateTime are compared, other types return false.

    Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)
  - toString
```
public String toString()
```
    Outputs this date-time as a String, such as 2007-12-03T10:15:30+01:00.
    The output will be one of the following ISO-8601 formats:
    - uuuu-MM-dd'T'HH:mmXXXXX
    - uuuu-MM-dd'T'HH:mm:ssXXXXX
    - uuuu-MM-dd'T'HH:mm:ss.SSSXXXXX
    - uuuu-MM-dd'T'HH:mm:ss.SSSSSSXXXXX
    - uuuu-MM-dd'T'HH:mm:ss.SSSSSSSSSXXXXX
    The format used will be the shortest that outputs the full value of the time where the omitted parts are implied to be zero.
    覆盖:
    
    toString 在类中 Object
    
    返回:
