Getting the client's timezone in JavaScript

Question

How can I gather the visitor's time zone information? I need the GMT offset hours.

Answer 1

try getTimeZoneOffset() of the Date object:

var curdate = new Date()
var offset = curdate.getTimeZoneOffset()

this method return time zone offset in minutes which is the difference between GMT and local time.

Answer 2

var offset = new Date().getTimezoneOffset();

The time-zone offset is the difference, in minutes, between UTC and local time. Note that this means that the offset is positive if the local timezone is behind UTC and negative if it is ahead. For example, if your time zone is UTC+10 (Australian Eastern Standard Time), -600 will be returned. Daylight savings time prevents this value from being a constant even for a given locale

• Mozilla Date Object reference

Note that not all timezones are offset by whole hours: for example, Newfoundland is UTC minus 3h 30m (leaving Daylight Saving Time out of the equation).

Answer 3

BTW, the function is 'getTimezoneOffset()' with a small 'z' (as in the top post). Thanks ,the approach was useful.
