Moment js showing wrong time when i format

I'm trying to convert java datetime instant to hh:mm format using moment js 

moment("2020-03-21T17:34:00Z").utcOffset(-0500).format("hh:mm")

it should give me 12:34, but somehow it is giving "12:14" which is the wrong time.

A few things:

  • The utcOffset function behaves differently whether you pass a string or a number. As a number, it's expected to be in terms of minutes. Since you have hours and minutes in your offset, you should pass it as a string: .utcOffset("-0500")

  • Format strings are case sensitive. You should use HH:mm (24-hour time), or hh:mm a (12-hour time). Since you used hh:mm without an a, anything after 12 pm will be misrepresented.

  • You are supplying a fixed offset. If that is your intent, then ok. But do recognize that there is a difference between an offset and a time zone. (See "Time Zone != Offset" in the timezone tag wiki.) For example, if you wanted to convert to US Eastern Time, you should use .tz('America/New_York) instead of .utcOffset("-0500"). (US Eastern time is at -4 for the date given, not -5.) You would need the moment-timezone addon to make this work.

  • Lastly, recognize that Moment is in maintenance mode. The moment team generally recommends Luxon for new development.

The moment js .utcOffset() method takes the offset in minutes.

so if you want to get 12:34 you need to use -300 instead of -0500

moment("2020-03-21T17:34:00Z").utcOffset(-300).format("hh:mm")
