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

OffsetDateTime.ofInstant介绍

[英]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.
[中]从即时和区域ID获取OffsetDateTime的实例。
这将创建一个与指定时间相同的偏移日期时间。查找UTC/格林威治的偏移量很简单，因为每个瞬间只有一个有效偏移量。
