Chatham Island Standard Time Zone - CHAST

Chatham Island Standard Time is twelve hours and forty-five minutes ahead of Coordinated Universal Time standard, written as an offset of UTC + 12:45. That means to find the standard time in the zone, you must add twelve hours and forty-five minutes to Coordinated Universal Time.

This is a nonstandard time zone, designated so because the incremental difference is not in whole hours but instead smaller.

Territories observing the time zone are primarily in the central Pacific. It runs through the Chatham Islands which are considered part of New Zealand.

During fall to winter months Chatham Island Standard Time is used, and then during Daylight Saving (spring to summer months) Chatham Island Daylight Time or CHADT is used.
