本文整理了Java中java.time.OffsetDateTime.withOffsetSameInstant()方法的一些代码示例，展示了OffsetDateTime.withOffsetSameInstant()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。OffsetDateTime.withOffsetSameInstant()方法的具体详情如下：
包路径：java.time.OffsetDateTime
类名称：OffsetDateTime
方法名：withOffsetSameInstant

OffsetDateTime.withOffsetSameInstant介绍

[英]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 LocalDateTimeadjusted 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.

This instance is immutable and unaffected by this method call.
[中]返回具有指定偏移量的此OffsetDateTime的副本，确保结果在同一时刻。
此方法返回具有指定ZoneOffset和LocalDateTimeadjusted（由两个偏移量之间的差值调整）的对象。这将导致新旧对象代表同一时刻。这对于在不同偏移中查找本地时间很有用。例如，如果此时间表示2007-12-03T10:30+02:00，且指定的偏移量为+03:00，则此方法将返回2007-12-03T11:30+03:00。
要更改偏移量而不调整本地时间，请使用#withOffsetSameLocal。
此实例是不可变的，不受此方法调用的影响。
