本文整理了Java中io.opencensus.common.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：io.opencensus.common.Timestamp
类名称：Timestamp

Timestamp介绍

[英]A representation of an instant in time. The instant is the number of nanoseconds after the number of seconds since the Unix Epoch.

Use Tracing.getClock().now() to get the current timestamp since epoch (1970-01-01T00:00:00Z).
[中]一个瞬间在时间上的表现。instant是自Unix时代以来的秒数之后的纳秒数。
使用追踪。getClock（）。now（）获取自epoch（1970-01-01T00:00:00Z）以来的当前时间戳。
