the changeover from Dublin time to Greenwich time was simultaneous with the changeover from summer time to winter time. John Dillon opposed the first reading of the Time (Ireland) Bill for having been introduced without consultation of the Irish Parliamentary Party; he said the different time in Ireland "reminds us that we are coming into a strange country". T. M. Healy opposed the second reading on the basis that "while the Daylight Saving Bill added to the length of your daylight, this Bill adds to the length of your darkness". After the Irish Free State became independent in 1922, subsequent developments tended to mirror those in the United Kingdom. This avoided having different times on either side of the border with Northern Ireland. Summer time was provided on a one-off basis by acts in 1923 and 1924, and then on an ongoing basis by the Summer Time Act, 1925. The 1925 Act provided a default summer time period, which could be varied by ministerial order. Double summer time was considered but not introduced during the Emergency of World War II. As a consequence, following the introduction of double summer time in the United Kingdom in 1940, Northern Ireland was one hour ahead of the Republic of Ireland throughout the year until the UK returned to GMT in the autumn of 1947. From 1968 standard time (GMT+01:00) was observed all year round, with no winter time change. This was an experiment in the run-up to Ireland's 1973 accession to the EEC, and was undone in 1971. In those years, time in Ireland was the same as in the six EEC countries, except in the summer in Italy, which switched to Central European Summer Time (CEST). One artefact of the 1968 legislation is that "standard time" legally refers to summer time; the 1971 act defined a period of time in the winter as "winter time" during which the time observed would be GMT, leaving "standard time" unchanged. From the 1980s, the dates of switch between winter and summer time have been synchronised across the European Union. Orders The statutory instruments (SIs) that have been issued under the Standard Time Acts are listed below, in the format year/SI-number, and linking to the Irish Statute Database text of the SI. Except where stated, those issued up to 1967 (under the 1925 Act) were called "Summer Time Order <year>", while those issued from 1981 (under
