本文整理了Java中com.google.cloud.Timestamp类的一些代码示例，展示了Timestamp类的具体用法。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。Timestamp类的具体详情如下：
包路径：com.google.cloud.Timestamp
类名称：Timestamp

Timestamp介绍

[英]Represents a timestamp with nanosecond precision. Timestamps cover the range [0001-01-01, 9999-12-31].

Timestamp instances are immutable.
[中]表示纳秒精度的时间戳。时间戳覆盖范围为[0001-01-019999-12-31]。
时间戳实例是不可变的。
