UTC+11:30 is an identifier for a +11:30 hour time offset from UTC. This timezone has been used as standard time in Norfolk Island and New Zealand, but is no longer used as a time zone anywhere.
Historical use
On November 2, 1868, New Zealand officially adopted a standard time to be observed nationally, and was perhaps the first country to do so. It was based on the longitude 172° 30' East of Greenwich, that is 11 hours 30 minutes ahead of Greenwich Mean Time. This standard was known as New Zealand Mean Time (NZMT).[1] Today this would be around the same zone covered by UTC+11:30. New Zealand changed from NZMT to New Zealand Standard Time (NZST) as GMT+1200 in 1946 (after using this timezone as a daylight saving time since 1928, including permanent daylight saving from 1941).[2] It was officially changed to 12 hours in advance of UTC in 1974.[3]
Norfolk Island's standard time (NFT) was on UTC+11:30 until 4 October 2015, when it was changed to UTC+11:00.[4]
