I'm on the Pacific Coast (PST) -8 hours (-420 minutes) from UTC and

var d = new Date();
var n = d.getTimezoneOffset();

returns 420. Shouldn't it return -420?

I'm trying to calculate a local time to save on the server by passing a local utcoffset. My server is in UTC time

so I wanted to do something like

group.DateCreatedLocalTime = DateTime.UtcNow.AddMinutes(viewModel.UtcOffset);

but if the time is 420 and not -420 then how will I know to add or subtract minutes from DateTime.UtcNow?

  • so I assume I need to subtract minutes, instead of add minutes? – chuckd Aug 08 '18 at 04:20

In Javascript You can use setMinutes() function.

Example : 

var d = new Date();
var n = d.getTimezoneOffset();
d.setMinutes(d.getMinutes() - n);

you can subtract this way.
