Get date time for a specific time zone using JavaScript
提问by Yang
It seems that JavaScript's Date() function can only return local date and time. Is there anyway to get time for a specific time zone, e.g., GMT-9?
JavaScript 的 Date() 函数似乎只能返回本地日期和时间。有没有办法获得特定时区的时间，例如 GMT-9？
Combining @?Esailija and @D3mon-1stVFW, I figured it out: you need to have two time zone offset, one for local time and one for destination time, here is the working code:
结合@?Esalija 和@D3mon-1stVFW，我想通了：你需要有两个时区偏移，一个用于本地时间，一个用于目的地时间，这是工作代码：
var today = new Date();
var localoffset = -(today.getTimezoneOffset()/60);
var destoffset = -4;
var offset = destoffset-localoffset;
var d = new Date( new Date().getTime() + offset * 3600 * 1000)
An example is here: http://jsfiddle.net/BBzyN/3/

var offset = -8;
new Date( new Date().getTime() + offset * 3600 * 1000).toUTCString().replace( / GMT$/, "" )
"Wed, 20 Jun 2012 08:55:20"
<script>
var offset = -8;
document.write(
new Date(
new Date().getTime() + offset * 3600 * 1000
).toUTCString().replace( / GMT$/, "" )
);

You can do this in one line:
您可以在一行中执行此操作：
let d = new Date(new Date().toLocaleString("en-US", {timeZone: "timezone id"})); // timezne ex: Asia/Jerusalem

You can always get GMT time (so long as the client's clock is correct).
您始终可以获得 GMT 时间（只要客户的时钟是正确的）。
To displaya date in an arbitrary time-zone, construct a string from the UTC hours, minutes, and seconds after adding the offset.
要在任意时区显示日期，请在添加偏移量后根据 UTC 小时、分钟和秒构造一个字符串。
