Java 8：如何从Epoch值创建ZonedDateTime？ [英] Java 8: How to create a ZonedDateTime from an Epoch value?

问题描述

Java 8的 LocalDateTime 有一个 ofEpochSecond 方法。不幸的是， ZonedDateTime 中没有这样的方法。现在，我有一个Epoch值和一个明确的 ZoneId 。如何从这些中获得 ZonedDateTime ？

Java 8's LocalDateTime has an ofEpochSecond method. Unfortunately, there is no such method in the ZonedDateTime. Now, I have an Epoch value and an explicit ZoneId given. How do I get a ZonedDateTime out of these?

推荐答案

你应该能够通过 Instant 类来完成此操作，该类可以代表给定纪元时间的时刻。如果你有纪元秒，你可以通过类似

You should be able to do this via the Instant class, which can represent a moment given the epoch time. If you have epoch seconds, you might create something via something like

Instant i = Instant.ofEpochSecond(t);
ZonedDateTime z = ZonedDateTime.ofInstant(i, zoneId);
