*For [moment.js][] users, you can now use [moment-timezone][] .* **对于[moment.js][]用户，您现在可以使用[moment-timezone][] 。** *Using it, your function would look something like this:* **使用它，您的函数将如下所示：**

function toTimeZone(time, zone) {
        var format = 'YYYY/MM/DD HH:mm:ss ZZ';
        return moment(time, format).tz(zone).format(format);

除Safari外，大多数桌面（非移动）浏览器都支持带参数的[toLocaleString][]函数，较旧的浏览器通常会忽略该参数。

new Date().toLocaleString('en-US', { timeZone: 'Asia/Jakarta' })

*Got it !* **得到它了 ！**

*Wanted to force the date shown = server date, no mattter the local settings (UTC).* **想要强制显示的日期=服务器日期，不影响本地设置（UTC）。**

*My server is GMT-6 --> new Date().getTimezoneOffset() = 360.* **我的服务器是GMT-6-> new Date（）。getTimezoneOffset（）= 360。**

myTZO = 360;
    myNewDate=new Date(myOldDateObj.getTime() + (60000*(myOldDateObj.getTimezoneOffset()-myTZO)));
    alert(myNewDate);
