moment js is returning wrong formatted values for an iso timestamp

Question

I\'m passing \"2018-01-31T22:55:02.907Z\" this timestamp to the moment() function but it returns the wrong value after formatting the date part.

Answer 1

You have to use .utc when passing timestamp like this: If you do:

console.log(moment("2018-01-31").format('YYYY-MM-DD'));

It would give you the desired result but when passing timestamp like you have done now, what you should do is:

console.log(moment.utc("2018-01-31T22:55:02.907Z").format('YYYY-MM-DD'));

You can also see how this works:

console.log(moment({ years:2018, months:0, date:31, hours:22, minutes:55, seconds:02, milliseconds:907}).format('YYYY-MM-DD'));

For passing timestamp you should check the documentation again. https://momentjs.com/docs/#/parsing/unix-timestamp-milliseconds/

Answer 2

You have to use moment.utc():

By default, moment parses and displays in local time.

If you want to parse or display a moment in UTC, you can use moment.utc() instead of moment().

console.log(moment("2018-01-31T22:55:02.907Z").format('YYYY-MM-DD'));
console.log(moment.utc("2018-01-31T22:55:02.907Z").format('YYYY-MM-DD'));
