本文整理了Java中io.opencensus.common.Duration类的一些代码示例，展示了Duration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。Duration类的具体详情如下：
包路径：io.opencensus.common.Duration
类名称：Duration

Duration介绍

[英]Represents a signed, fixed-length span of time represented as a count of seconds and fractions of seconds at nanosecond resolution. It is independent of any calendar and concepts like "day" or "month". Range is approximately +-10,000 years.
[中]表示有符号、固定长度的时间跨度，以纳秒分辨率表示为秒数和秒分数。它独立于任何日历和“日”或“月”等概念。范围约为+-10000年。
