Chatham Island Daylight Time Zone - CHADT

Chatham Island Daylight Time is thirteen hours and forty-five minutes ahead of Coordinated Universal Time standard, written as an offset of UTC + 13:45. That means to find the standard time in the zone, you must add thirteen 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. Those in the zone actually refer to it as Chatham Daylight Time or CDT.

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