Time To Change

In 1880, the Statutes Act deemed that ‘Dublin Mean Time’, as opposed to ‘Greenwich Mean Time’, was the legal time for all of Ireland. Dublin Mean Time was, for some reason, exactly 25 minutes and 21 seconds behind the local time in Britain. After the Easter Rising of 1916 everyone realised that this was not only confusing, but also impractical for telegraphic communications, and the time zones were switched back to coincide with British time.
