Can I set the local timezone in my browser via Javascript?
提问by Douglas Mauch
I know I can get the local timezone offset via new Date().getTimeZoneOffset(). But where did Javascript get that information? Is there a way I can set it, so that all future Date objects have the offset I want? I tried searching the DOM in Firebug, but couldn't find anything.
我知道我可以通过 new Date().getTimeZoneOffset() 获取本地时区偏移量。但是 Javascript 从哪里获得这些信息呢？有没有办法设置它，以便所有未来的 Date 对象都具有我想要的偏移量？我尝试在 Firebug 中搜索 DOM，但找不到任何东西。
What I am trying to accomplish is converting epoch times to readable format, but it needs to be in US/Central, no matter what the browser's OS setting. Because I am using US/Central, it's not a fixed difference from GMT. So instead of a bunch of super nasty conversion steps, why can't I just tell Javascript that I'm actually in US/Central?
我想要完成的是将纪元时间转换为可读格式，但无论浏览器的操作系统设置如何，它都需要在美国/中部。因为我使用的是 US/Central，所以它与 GMT 没有固定的区别。因此，为什么我不能告诉 Javascript 我实际上在美国/中部，而不是一堆超级讨厌的转换步骤？

An implementation of ECMAScript is expected to determine the local time zone adjustment.

No.
不。

Have you considered using a library?
你考虑过使用图书馆吗？

Currently, Moment-Timezone enables us to set the "browser's" default timezone by using moment.tz.setDefault().
目前，Moment-Timezone 使我们能够使用moment.tz.setDefault().
You'll have to use moment()instead of Date(), but this is still a nice upgrade over the weird JS Date object.
你必须使用moment()而不是Date()，但这仍然是对奇怪的 JS Date 对象的一个很好的升级。
