Java 8：如何从 Epoch 值创建 ZonedDateTime？

Java 8: How to create a ZonedDateTime from an Epoch value?

提问by rabejens

Java 8's LocalDateTimehas an ofEpochSecondmethod. Unfortunately, there is no such method in the ZonedDateTime. Now, I have an Epoch value and an explicit ZoneIdgiven. How do I get a ZonedDateTimeout of these?

Java 8LocalDateTime有一个ofEpochSecond方法。不幸的是，在ZonedDateTime. 现在，我有一个 Epoch 值和一个明确的ZoneId给定值。我如何ZonedDateTime摆脱这些？

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

您应该能够通过Instant类来做到这一点，它可以代表给定纪元时间的一个时刻。如果你有纪元秒，你可能会通过类似的东西创建一些东西

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