1880年開始,爱尔兰擁有獨立的时区,称都柏林标准时间(Dublin standard time)。这是都柏林顿兴克天文台(英语:Dunsink Observatory)的当地时间,比格林尼治时间慢大约25分21秒。[5][7][8]复活节起义后,爱尔兰从英国独立,两国间的时差给电报等業務带来了不便。都柏林标准时间1916年10月1日2:00開始,爱尔兰回到了英国的时区。[5]
2018年3月8日,欧洲议会发起向欧盟委员会请求重新制定欧洲夏令时的投票。[17]参与网上调查的民众中有84%反对欧盟一年变换两次时区。[18]9月12日,欧盟委员会决定停用根据季节变换时区的行为,并按照欧盟立法程序(英语:European Union legislature procedure)修改时区规定。[19]由于那时英国已经退出欧盟且没有遵守修订后的规定,而北爱尔兰是英国的一部分,这将令爱尔兰岛上的两个国家每年有半年处在相差半小时的状态,并加重英国-爱尔兰边境问题(英语:Brexit and the Irish border)的态势。[20]2018年11月,爱尔兰司法与平等部(英语:Department of Justice and Equality)举办了有关季节时间的磋商会。[21]截至2018年9月,英国政府仍没有改变北爱尔兰现有时间规定的计划。[22]
欧洲议会议员肖恩·凯利(英语:Seán Kelly (Irish politician))曾游说欧盟取消夏令时;另一方面,他支持爱尔兰全年采用夏令时,即欧洲西部时间[23];由于爱尔兰经度偏西,假如爱尔兰全年采用夏令时,那么太阳将会在当地时间上午9:40升起,而不是现在规定的8:40。这一现象可能会导致生活的不便,类似中国在西部推行北京时间的问题。
