The Info List - Central European Time

Central European Time
Central European Time
(CET), used in most parts of Europe
and a few North African
North African
countries, is a standard time which is 1 hour ahead of Coordinated Universal Time
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, Romance Standard Time (RST), Paris Time or Rome Time.[1] The 15th meridian east
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). A number of African countries use UTC+01:00 all year long, where it is called West Africa Time
West Africa Time
(WAT), although Algeria
and Tunisia
also use the term Central European Time.[citation needed]

Under German occupation:

The Netherlands
was switched from UTC+00:20 to CET. Belgium
was switched from UTC+00:00. Luxembourg
was switched from UTC+00:00.

France, which had adopted Paris time on 14 March 1891 and Greenwich Mean Time on 9 March 1911,[4] was switched to CET.

After World War II Monaco, Andorra
and Gibraltar
implemented CET. Spain
switched to CET in 1940. Portugal used CET in the years 1966–1976 and 1992–1996.

United Kingdom

The time around the world is based on Universal Coordinated Time
Universal Coordinated Time
(UTC) which is roughly synonymous with Greenwich Mean Time
Greenwich Mean Time
(GMT). From late March to late October, clocks in the United Kingdom
United Kingdom
are put forward by one hour for British Summer Time
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.[citation needed] Central European Time
Central European Time
is sometimes referred to as continental time in the UK. Other countries[edit] Several African countries use UTC+01:00 all year long, where it called West Africa Time
West Africa Time
(WAT), although Algeria
and Tunisia
also use the term Central European Time, despite being located in North Africa.[citation needed] 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. For other countries see UTC+01:00 and West Africa Time. Discrepancies between official CET and geographical CET[edit]

Legal, political and economic, as well as physical or geographical criteria are used in the drawing of time zones so official time zones rarely adhere to meridian lines. The CET time zone, were it drawn by purely geographical terms, would consist of exactly the area between meridians 7°30′ E and 22°30′ E. As a result, there are European locales that despite lying in an area with a "physical" UTC+1 time, actually use another time zone (UTC+2 in particular – there are no "physical" UTC+1 areas that employ UTC). Conversely, there are European areas that have gone for UTC+1, even though their "physical" time zone is UTC
(typically), UTC−1 (westernmost Spain), or UTC+2 (e.g. the very easternmost parts of Norway, Sweden, Poland
and Serbia). On the other hand, the people in Spain
still have all work and meal hours one hour later than France
and Germany
even if they have the same time zone.[citation needed] Following is a list of such "incongruences": Historically Gibraltar
maintained UTC+1 all year until the opening of the land frontier with Spain
in 1982 when it followed its neighbour and introduced CEST. Areas located within UTC+1 longitudes using other time zones[edit] These areas are located between 7°30′ E and 22°30′ E ("physical" UTC+1) Areas using UTC+2[edit]

Areas located outside UTC+1 longitudes using UTC+1 time[edit] These areas are located west of 7°30′ E or east of 22°30′ E (outside "physical" UTC+1) Areas between 22°30′ W and 7°30′ W ("physical" UTC−1)[edit]

The westernmost part of mainland Spain
(Galicia, e.g. the city of A Coruña); Cape Finisterre

Jan Mayen
lies entirely within this area and extends nearly as far west as Cape Finisterre, with its western tip at 9°5′ W and its eastern tip at 7°56′ W.

Map of Petsamo area in northern Finland/Soviet Union/Russia. The green area is the Finnish part of the Rybachi peninsula (Kalastajasaarento) which was ceded to the Soviet Union after the Winter War. The Red area is the Jäniskoski-Niskakoski area ceded to the USSR in 1947.

The northeast of Norway, lying north of Finland, roughly coinciding with the county of Finnmark; for instance Vadsø, the capital of Finnmark, has a longitude of 29°49′ E. Actually, the easternmost town in Norway, Vardø, lies at 30°51′ E, which is so far east, so as to be east even of the central meridian of EET (UTC+2), i.e. east of Istanbul
and Alexandria. The sun reaches its highest point at 10:56 (when not DST). The Norwegian–Russian and the Polish-Belarussian border are the only places where CET (UTC+1/+2) borders Moscow time (UTC+3), resulting in a two hours time change (or one hour in summer) for the passenger crossing that border. More so, there exists a "tri-zone" point (where UTC+1, UTC+2, and UTC+3 meet) at the Norway–Finland– Russia
tripoint near Muotkavaara. Mental experiment when looking at this map: Go to the westernmost point of the red area (the Jäniskoski-Niskakoski area); this belongs to Russian jurisdiction, hence the time there is UTC+3. Then, take a northeastern (NE) direction (that is an eastwards direction).
