Daylight saving time was introduced by the Summer Time Act 1916 and implemented on 1 October 1916 as GMT plus one hour and Dublin Mean Time plus one hour. However, Dublin Mean Time (used by the railways) had a disparity of twenty-five minutes with Greenwich Mean Time, which meant that the Bangor Railway Station Clock was to be put back only thirty-five minutes instead of one hour.
