问题描述

如何在Node.js中获得最准确的时间戳?

How can I get the most accurate time stamp in Node.js?

ps我的Node.js版本是0.8.X和对我不起作用(安装时崩溃)

ps My version of Node.js is 0.8.X and the node-microtime extension doesn't work for me (crash on install)

推荐答案

new Date()。getTime()?这给你一个以毫秒为单位的时间戳,这是JS给你的最准确的。

new Date().getTime()? This gives you a timestamp in milliseconds, which is the most accurate that JS will give you.

更新:如vaughan所述, process.hrtime ()在Node.js中可用 - 它的分辨率是纳秒,因此它的分辨率要高得多,这并不意味着它必须更精确。

Update: As stated by vaughan, process.hrtime() is available within Node.js - its resolution are nanoseconds and therefore its much higher, also this doesn't mean it has to be more exact.

PS:为了更清楚, process.hrtime()返回一个元组数组包含当前高分辨率实时,[秒,纳秒]

PS.: Just to be clearer, process.hrtime() returns you a tuple Array containing the current high-resolution real time in a [seconds, nanoseconds]
