Time in the Republic of Ireland
Appearance
Ireland uses Western European Time (UTC) in the summer period, and Irish Standard Time or Western European Summer Time (UTC+1) in the winter months.
History
The Standard Time Act 1968 [1] stipulated that standard time is UTC+1 (CET) and from 1968 clocks were not turned back one hour during winter. The subsequent Standard Time (Amendment) Act, 1971 [2] effectively reversed this, and from 1971 returned winter time to UTC+0 (Western European Time), it did not however change the names of the Irish summer time zone, which are still, officially, Irish Standard Time (IST) and Am Caighdeánach na hÉireann (ACÉ).
