UTC Offset: UTC-12
What is UTC-12?
UTC-12 is a fixed offset from Coordinated Universal Time: clocks on this offset are always 12 hours behind UTC. Unlike a named time zone, a UTC offset never shifts for daylight saving time. Regions that observe DST alternate between two different UTC offsets across the year, which is why the countries listed below can change with the seasons.
In aviation, shipping, and military usage, UTC-12 corresponds to the Yankee time zone (Y), written with the letter suffix Y in Zulu notation. Pilots and NATO forces use these letter zones so an order like "0800Y" is unambiguous worldwide.
UTC-12 vs GMT-12
On a wall clock, UTC-12 and GMT-12 show the same time. The difference is in what they refer to: UTC is the modern standard kept by atomic clocks and used in computing, aviation, and science, while GMT is the older convention based on mean solar time at Greenwich. Technical systems, logs, and APIs should reference UTC-12.
