UTC−00:25:21 is an identifier for a time offset from UTC of −00:25:21, i.e. twenty-five minutes and twenty-one seconds behind Greenwich Mean Time. This time, known as Dublin Mean Time, is local mean time at Dunsink Observatory and was official time in Ireland between 1880 and 1916.
History
[edit]Dublin Mean Time was introduced by the Statutes (Definition of Time) Act, 1880,[1] which also defined Greenwich Mean Time (GMT) as legal time in Great Britain. This act replaced local mean time, which had been the legal time since Curtis v. March in 1858, throughout the United Kingdom of Great Britain and Ireland.
From 3:00 DST on 1 October 1916, the Time (Ireland) Act, 1916[2] changed the time used in Ireland to be the same as that used in Great Britain, both during and outside daylight saving time.
