    Central European Time (CET), used in most parts of Europe and a few North African countries, is a standard time which is 1 hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as +01:00. The same standard time, UTC+01:00, is also known as Middle European Time (MET, German: MEZ) and under other names like Berlin Time, Warsaw Time and Romance Standard Time (RST), Paris Time or Rome Time.[1]

    The 15th meridian east is the central axis for UTC+01:00 in the world system of time zones.

    As of 2011, all member states of the European Union observe summer time; those that during the winter use CET use Central European Summer Time (CEST) (or: UTC+02:00, daylight saving time) in summer (from last Sunday of March to last Sunday of October).[2]

    A number of African countries use UTC+01:00 all year long, where it is called West Africa Time (WAT)[3], although Algeria, Morocco and Tunisia also use the term Central European Time.[4]

    United Kingdom

    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[25] 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.[26]

    Central European Time is sometimes referred to as continental time in the UK.

    Other countries

    Several African countries use UTC+01:00 all year long, where it called West Africa Time (WAT), although Algeria, Morocco and Tunisia also use the term Central European Time, despite being located in North Africa.[4]

    Between 2005 and 2008, Tunisia observed daylight saving time.[27] Libya also used CET during the years 1951–1959, 1982–1989, 1996–1997 and 2012–2013.

    For other countries see UTC+01:00 and West Africa Time.
