如果 javascript "(new Date()).getTime()";从 2 个不同的时区运行

2022-01-16 00:00:00 datetime timezone javascript

如果 JavaScript (new Date()).getTime() 同时从 2 个不同的时区运行，你会得到相同的值吗?

If JavaScript (new Date()).getTime() is run from 2 different timezones simultaneously, will you get the same value?

这个值是否会受到运行浏览器的机器上设置的系统时间的影响?

Will this value be affected by the system time set on the machine where the browser is running?

推荐答案

是的，受系统时间影响.但是，如果本地时间是正确的(对于计算机设置的任何时区)，它在任何时区都应该是相同的.

Yes, it's affected by system time. However, if the local time is correct (for whatever time zone the computer's set to), it should be the same in any time zone.

ECMAScript 标准说(§15.9.1.1):

The ECMAScript standard says (§15.9.1.1):

"时间是在 ECMAScript 中测量的自 1970 年 1 月 1 日以来的毫秒数UTC."

"Time is measured in ECMAScript in milliseconds since 01 January, 1970 UTC."
