Chatham is on UTC+13:45 (UTC+13:45) now.

No zone keeps UTC+12:45 all year, so the clock above shows Chatham, which uses CHAST from the first Sunday of April at 3:45 AM to the last Sunday of September at 2:45 AM.

What CHAST means

CHAST stands for Chatham Standard Time, UTC+12:45. It is used in the Chatham Islands of New Zealand.

It is a standard (winter) time. Places on CHAST that observe daylight saving time switch to CHADT (UTC+13:45) in summer, so CHAST is a fixed offset while the local clock is not.

tzdata, the database behind phones and computers, does not use the letters CHAST: it writes UTC+12:45 for this time. CHAST is the customary or CLDR name, so software may show “UTC+12:45” or “GMT+12:45” instead.

Where and when CHAST is used

1 zone uses it for part of the year only, switching to daylight saving time in the other months. Computed from tzdata under the current rules (tzdata writes UTC+12:45; the list follows the CLDR name).

Every column is a fixed offset, so this table is valid on any date. Remember that the regions behind some columns switch to summer time (EST to EDT, CET to CEST, GMT to BST); the clock in those cities is then an hour later than the column.
