如何从javascript中的UTC时间偏移量中知道时区名称

Question

How to know the timezone name from UTC offset in Javascript.

I have UTC offset, say

UTC+5:30, 

I need to know where this timezone location is, like I want to get 'Asia/Calcutta'.

If I give ' UTC+9 ' , then I need to get Asia/Tokyo

How to do this in Javascript?

Answer 1

You should be able to get that using Intl API. You can find the demo at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/DateTimeFormat/resolvedOptions

Answer 2

你可以试试：

console.log(Intl.DateTimeFormat().resolvedOptions().timeZone)
