将javascript中的unix日期时间戳转换为特定时区的时间

Question

I want to convert unix timestamp to time for a particular timezone.

say for example unix time stamp is - 1446960600 I want to convert this timestamp to America/Los Angeles ?

Answer 1

You can convert a unix timestamp integer into a Javascript date like this

var date = new Date(1446960600 * 1000);

Unix timestamps are in the UTC timezone, but there isn't an easy way to do timezone changes in Javascript.

I recommend you use a time library like momentjs . It handles edge cases like daylight savings that you would have to take into account if you do it yourself.

Here's some sample code from another answer:

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

You can use the getTimezoneOffset() method of a DateTime to calculate the timezone change, but understand this won't take into account daylights saving or leap year changes.

Answer 2

Use momentjs. You can choose your format and you just set the country you need
