moment().utcOffset(); moment().utcOffset(Number|String);

---

Get the utc offset in minutes.

NOTE: Unlike moment.fn.zone this function returns the real offset from UTC, not the reverse offset (as returned by Date.prototype.getTimezoneOffset).

Getting the utcOffset of the current object:

moment().utcOffset(); // (-240, -120, -60, 0, 60, 120, 240, etc.)

Setting the utc offset by supplying minutes. Note that once you set an offset, it's fixed and won't change on its own (i.e there are no DST rules). If you want an actual time zone -- time in a particular location, like America/Los_Angeles, consider moment-timezone.

moment().utcOffset(120);

If the input is less than 16 and greater than -16, it will interpret your input as hours instead.

// these are equivalent
moment().utcOffset(8);  // set hours offset
moment().utcOffset(480);  // set minutes offset (8 * 60)

It is also possible to set the utc offset from a string.

// these are equivalent
moment().utcOffset("+08:00");
moment().utcOffset(8);
moment().utcOffset(480);

moment#utcOffset will search the string for the first match of +00:00 +0000 -00:00 -0000, so you can even pass an ISO8601 formatted string and the moment will be changed to that utc offset.

Note that the string is required to start with the + or - character. Passing a string that does not start with + or - will be interpreted as if it were "+00:00".

moment().utcOffset("2013-03-07T07:00:00+08:00");
