Time in the Republic of Ireland to be the legal time for Great Britain. After the Easter Rising, the time difference between Ireland and Britain was found inconvenient for telegraphic communication and the Time (Ireland) Act, 1916 provided that Irish time would be the same as British time, from 2:00 am Dublin Mean Time on Sunday 1 October 1916. Summer time (daylight saving time) had been introduced in May 1916 across the United Kingdom as a temporary efficiency measure for the First World War, and the changeover from Dublin time to Greenwich time was simultaneous with the changeover from summer time to winter time.

Earl of Drogheda of his brother-in-law, Henry Hamilton, 2nd Earl of Clanbrassil. In a feast of egotism, he built and named Henry Street, Moore Street, Earl Street, Of (or Off) Lane (now Henry Place, and an important escape route for the volunteers fleeing the GPO during the Easter Rising in 1916), and Drogheda Street (part of what is now O'Connell Street). The third Earl was succeeded by his grandson Henry, the fourth Earl. The latter died without surviving children at an early age and was succeeded by his younger brother, Edward, the fifth Earl, who had previously represented Dunleer in the Irish Parliament.
