Time Zone History - Chatham Islands

The Chatham Islands standardized their time in 1868 to 12 hours and 15 minutes ahead of Greenwich Mean Time (GMT), then the world's time standard.

Even though the Standard Time Act 1945 set the time in New Zealand to UTC+12, the Chatham Islands informally set their clocks 45 minutes forward of the mainland. In 1956, New Zealand’s Parliament formalized the time difference by amending the Standard Time Act 1945. The law was effective from January 1, 1957.

Daylight Saving Time (DST) was introduced to the Chatham Islands and New Zealand in 1974 with the Time Act 1974.
