时区时区解释特定时区中的日期

Question

If I want to build a moment object, representing a timestamp in certain time zone, eg 2019/04/13 00:00:00 at time zone Europe/Berlin, how do I do it right?

What I'm trying to do:

moment.tz.setDefault('Europe/Berlin');
const m = moment('2019/04/13 00:00:00');

which results in m being set to Sat Apr 13 2019 02:00:00 GMT+0200 (Central European Summer Time) - 2 hours ahead of what I need. What I need is 00:00:00 not 02:00:00.

What is the reasoning behind this behavior? How do I tell moment-timezone "take this date and time and interpret it as if it is in the time zone I say"?

Per your comment, following is a snippet that demonstrates how to apply the answer from the duplicate question.

 const berlin = moment.tz('2019/04/13 00:00:00', 'YYYY/MM/DD hh:mm:ss', 'Europe/Berlin'); console.log('UTC', berlin.utc().format()); // UTC 2019-04-12T22:00:00Z console.log('Europe/Berlin', berlin.tz('Europe/Berlin').format()); // Europe/Berlin 2019-04-13T00:00:00+02:00
