The time around the world is based on Universal Coordinated Time (UTC) which is roughly synonymous with Greenwich Mean Time (GMT). From late March to late October, clocks in the United Kingdom are put forward by one hour for British Summer Time (BST). Since 1997, most of the European Union aligned with the British standards for BST.
In 1968 there was a three-year experiment called British Standard Time, when the UK and Ireland experimentally employed British Summer Time (GMT+1) all year round; clocks were put forward in March 1968 and not put back until October 1971.
Central European Time is sometimes referred to as continental time in the UK.
Several African countries use UTC+01:00 all year long, where it called West Africa Time (WAT), although Algeria and Tunisia also use the term Central European Time, despite being located in North Africa.
Between 2005 and 2008, Tunisia observed daylight saving time. Libya also used CET during the years 1951–1959, 1982–1989, 1996–1997 and 2012–2013.
