Check the table for the full name of world time zones and their abbreviated form, in alphabetical order, as well as GMT/UTC offset values. Please advise us of any changes using the feedback form at the bottom of this page.

Note: Certain abbreviations are used for different time zones, e.g IST is either India Standard Time or Irish Summer Time or Israel Standard Time. In some cases, when a country has multiple time zones, only the link to the general time page will be available, e.g Australia.

Clocks displayed for a certain time zone or country always show the current time for that area, adjusted automatically for local Daylight Saving Time (DST) rules. Click on a time zone link to view the time.
