==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)'''.<ref>{{cite web |url= http://www.paperspast.natlib.govt.nz/cgi-bin/paperspast?a=d&cl=search&d=EP19290408.2.88&srpos=2 |title=Evening Post — 8 April 1929 — OUR TIME |work=paperspast.natlib.govt.nz |year=2011 |accessdate=4 October 2015}}</ref> 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).<ref>{{cite web |url=http://www.dia.govt.nz/Daylight-Saving-History |title=Daylight Saving History |publisher=New Zealand Department of Internal Affairs |accessdate=4 October 2015}}</ref> It was officially changed to 12 hours in advance of UTC in 1974.<ref>{{cite web |url=http://www.dia.govt.nz/Daylight-Saving |title=Daylight Saving |publisher=New Zealand Department of Internal Affairs |accessdate=4 October 2015}}</ref>
[[Norfolk Island]]'s standard time ('''NFT''') was on UTC+11:30 until 4 October 2015, when it was changed to [[UTC+11:00]].<ref>{{cite press release |last=Hardgrave |first=Gary |date=3 September 2015 |url=http://regional.gov.au/territories/norfolk_island/administrator/media/2015/ni-a-mr-201526.aspx |title=Norfolk Island standard time changes 4 October 2015 |location= |publisher=[[List of administrative heads of Norfolk Island|Administrator of Norfolk Island]] |accessdate=4 October 2015}}</ref>
