Get current timestamp from specific timezone
提问by Toby
is there an easy way to get the unix timestamp in javascript from a specific timezone? for example i want the client send me an unix timestamp but i want to get it to match my timezone.
有没有一种简单的方法可以从特定时区获取 javascript 中的 unix 时间戳？例如，我希望客户端向我发送一个 unix 时间戳，但我想让它与我的时区相匹配。
thanks!
谢谢！

Why not simply send the date in UTC, and then convert to your timezone on the server?
为什么不简单地以 UTC 格式发送日期，然后在服务器上转换为您的时区？
var utcEpochSeconds = dateObj.getTime() + (dateObj.getTimezoneOffset() * 60000);

Use toISOStringto get a UTC timestamp.
使用toISOString获得UTC时间戳。
var date = new Date();
date.toISOString(); // EST would be 6 hour diff from GMT

In order for this to happen, you need to apply the timezone offset to the time, and then remove your offset from value (test this, I am guessing from memory):
为了实现这一点，您需要将时区偏移量应用于时间，然后从值中删除您的偏移量（测试这个，我是从记忆中猜测的）：
var now = new Date(),
offset = -(now.getTimezoneOffset() * 60 * 1000), // now in milliseconds
userUnixStamp = +now + offset;
Now offset from your own:
现在从你自己的抵消：
var now = new Date(),
offset = now.getTimezoneOffset() * 60 * 1000,
yourUnixStamp = userUnixStamp - offset;
