本文整理了Java中java.time.OffsetDateTime.atZoneSameInstant()方法的一些代码示例，展示了OffsetDateTime.atZoneSameInstant()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.atZoneSameInstant()方法的具体详情如下：
包路径：java.time.OffsetDateTime
类名称：OffsetDateTime
方法名：atZoneSameInstant

OffsetDateTime.atZoneSameInstant介绍

[英]Combines this date-time with a time-zone to create a ZonedDateTimeensuring 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(ZoneId). To use the offset as the zone ID, use #toZonedDateTime().
[中]将此日期时间与时区组合，以创建ZonedDateTime，确保结果具有相同的瞬间。
这将返回从该日期时间和指定时区形成的ZonedDateTime。此转换将忽略可见的本地日期时间，而是使用基础即时。这避免了任何与当地时间线间隔或重叠有关的问题。结果可能会有不同的字段值，例如小时、分钟甚至一天。
要尝试保留字段的值，请使用#atZoneSimilarLocal（ZoneId）。要使用偏移量作为分区ID，请使用#toZonedDateTime（）。
