Central Africa Time, or CAT, is a time zone used in central and southern Africa. Central Africa Time is two hours ahead of Coordinated Universal Time (UTC+02:00), which is the same as the adjacent South Africa Standard Time and Eastern European Time.
Eastern European Time (EET) is one of the names of UTC+02:00 time zone, 2 hours ahead of Coordinated Universal Time. The zone uses daylight saving time, so that it uses UTC+03:00 during the summer.
South African Standard Time (SAST) is the time zone used by all of South Africa, Botswana as well as Eswatini and Lesotho. The zone is two hours ahead of UTC (UTC+02:00) and is the same as Central Africa Time. Daylight saving time is not observed in either time zone. Solar noon in this time zone occurs at 30° E in SAST, effectively making Pietermaritzburg at the correct solar noon point, with Johannesburg and Pretoria slightly west at 28° E and Durban slightly east at 31° E. Thus, most of South Africa's population experience true solar noon at approximately 12:00 daily.

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 UTC+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.
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west and the Mediterranean Sea to the south. It comprises the westernmost part of Eurasia.
Standard time is the synchronization of clocks within a geographical area or region to a single time standard, rather than using solar time or a locally chosen meridian (longitude) to establish a local mean time standard. Historically, the concept was established during the 19th century to aid weather forecasting and train travel. Applied globally in the 20th century, the geographical areas became extended around evenly spaced meridians into time zones which (usually) centered on them. The standard time set in each time zone has come to be defined in terms of offsets from Universal Time. In regions where daylight saving time is used, that time is defined by another offset, from the standard time in its applicable time zones.
Coordinated Universal Time is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time at 0° longitude, and is not adjusted for daylight saving time. In some countries where English is spoken, the term Greenwich Mean Time (GMT) is often used as a synonym for UTC and predates UTC by nearly 300 years.
The 15th meridian east is the central axis for UTC+01:00 in the world system of time zones.
The meridian 15° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Europe, Africa, the Atlantic Ocean, the Southern Ocean, and Antarctica to the South Pole.
UTC+01:00, known simply as UTC+1, is a time offset that adds 1 hour to Coordinated Universal Time (UTC). This time is used in:
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).
Central European Summer Time (CEST), sometime referred also as Central European Daylight Time (CEDT), is the standard clock time observed during the period of summer daylight-saving in those European countries which observe Central European Time (UTC+01:00) during the other part of the year. It corresponds to UTC+02:00, which makes it the same as Central Africa Time, South African Standard Time and Kaliningrad Time in Russia.
UTC+02:00 is an identifier for a time offset from UTC of +02. In ISO 8601 the associated time would be written as 2019-02-07T23:28:34+02:00. This time is used in:
Daylight saving time (DST), also daylight savings time or daylight time and summer time, is the practice of advancing clocks during summer months so that evening daylight lasts longer, while sacrificing normal sunrise times. Typically, regions that use daylight saving time adjust clocks forward one hour close to the start of spring and adjust them backward in the autumn to standard time. In effect, DST causes a lost hour of sleep in the spring and an extra hour of sleep in the fall.
A number of African countries use UTC+01:00 all year long, where it is called West Africa Time (WAT),although Algeria, Morocco, and Tunisia also use the term Central European Time.
West Africa Time, or WAT, is a time zone used in west-central Africa; with countries west of Benin instead using Greenwich Mean Time. West Africa Time is one hour ahead of Coordinated Universal Time (UTC+01), which makes it the same as Central European Time (CET) during winter, or Western European Summer Time (WEST) and British Summer Time (BST) during the summer.
Algeria, officially the People's Democratic Republic of Algeria, is a country in the Maghreb region of North Africa. The capital and most populous city is Algiers, located in the far north of the country on the Mediterranean coast. With an area of 2,381,741 square kilometres (919,595 sq mi), Algeria is the tenth-largest country in the world, the world's largest Arab country, and the largest in Africa. Algeria is bordered to the northeast by Tunisia, to the east by Libya, to the west by Morocco, to the southwest by the Western Saharan territory, Mauritania, and Mali, to the southeast by Niger, and to the north by the Mediterranean Sea. The country is a semi-presidential republic consisting of 48 provinces and 1,541 communes (counties). It has the highest human development index of all non-island African countries.
Morocco, officially the Kingdom of Morocco, is a country located in the Maghreb region of North West Africa with an area of 710,850 km2 (274,460 sq mi). Its capital is Rabat, the largest city Casablanca. It overlooks the Mediterranean Sea to the north and the Atlantic Ocean to the west. Morocco claims the areas of Ceuta, Melilla and Peñón de Vélez de la Gomera, all of them under Spanish jurisdiction.
Central European Time is currently (updated 2017)used in Albania, Andorra, Austria, Belgium, Bosnia and Herzegovina, Croatia, Czech Republic, Denmark, France, Germany, Hungary, Italy, Kosovo, Liechtenstein, Luxembourg, North Macedonia, Malta, Monaco, Montenegro, Netherlands, Norway, Poland, San Marino, Serbia, Slovakia, Slovenia, Spain, Sweden and Switzerland.
Albania, officially the Republic of Albania, is a country in Southeast Europe on the Adriatic and Ionian Sea within the Mediterranean Sea. It shares land borders with Montenegro to the northwest, Kosovo to the northeast, North Macedonia to the east, Greece to the south and a maritime border with Italy to the west.
Andorra, officially the Principality of Andorra, also called the Principality of the Valleys of Andorra, is a sovereign landlocked microstate on the Iberian Peninsula, in the eastern Pyrenees, bordering France to the north and Spain to the south. Believed to have been created by Charlemagne, Andorra was ruled by the Count of Urgell until 988, when it was transferred to the Roman Catholic Diocese of Urgell, and the present principality was formed by a charter in 1278. It is known as a principality as it is a diarchy headed by two Princes: the Catholic Bishop of Urgell in Catalonia, Spain, and the President of France.
Austria, officially the Republic of Austria, is a country in Central Europe comprising 9 federated states. Its capital, largest city and one of nine states is Vienna. Austria has an area of 83,879 km2 (32,386 sq mi), a population of nearly 9 million people and a nominal GDP of $477 billion. It is bordered by the Czech Republic and Germany to the north, Hungary and Slovakia to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The terrain is highly mountainous, lying within the Alps; only 32% of the country is below 500 m (1,640 ft), and its highest point is 3,798 m (12,461 ft). The majority of the population speaks local Bavarian dialects as their native language, and German in its standard form is the country's official language. Other regional languages are Hungarian, Burgenland Croatian, and Slovene.
After World War II Monaco, Andorra and Gibraltar implemented CET.
Portugal used CET in the years 1966–1976 and 1992–1996.
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 1968there 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, Morocco and Tunisia also use the term Central European Time, despite being located in North Africa.
Between 2005 and 2008, Tunisia observed daylight saving time. –1959, 1982–1989, 1996–1997 and 2012–2013.Libya also used CET during the years 1951

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+01:00 time, actually use another time zone (UTC+02:00 in particular – there are no "physical" UTC+01:00 areas that employ UTC+00:00). Conversely, there are European areas that have gone for UTC+01:00, even though their "physical" time zone is UTC (typically), UTC−01:00 (westernmost Spain), or UTC+02:00 (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.Following is a list of such "incongruences":
Historically Gibraltar maintained UTC+01:00 all year until the opening of the land frontier with Spain in 1982 when it followed its neighbour and introduced CEST.
These areas are located between 7°30′ E and 22°30′ E ("physical" UTC+1)
These areas are located west of 7°30′ E or east of 22°30′ E (outside "physical" UTC+01:00)
A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time.
Western European Summer Time (WEST) is a summer daylight saving time scheme, 1 hour ahead of Greenwich Mean Time and Coordinated Universal Time. It is used in:
The Eastern Time Zone (ET) is a time zone encompassing part or all of 22 states in the eastern part of the contiguous United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama in Central America, and the Caribbean Islands.
Western European Time is a time zone covering parts of western and northwestern Europe. The following countries and regions use WET in winter months:
European Summer Time is the variation of standard clock time that is applied in most European countries in the period between spring and autumn, during which clocks are advanced by one hour from the time observed in the rest of the year, in order to make the most efficient use of seasonal daylight. It corresponds to the notion and practice of daylight saving time to be found in many other parts of the world.
The Atlantic Time Zone is a geographical region that keeps standard time—called Atlantic Standard Time (AST)—by subtracting four hours from Coordinated Universal Time (UTC), resulting in UTC−04:00. During part of the year, some portions of the zone observe daylight saving time, referred to as Atlantic Daylight Time (ADT), by moving their clocks forward one hour to result in UTC−03:00. The clock time in this zone is based on the mean solar time of the 60th meridian west of the Greenwich Observatory.
Moscow Time is the time zone for the city of Moscow, Russia, and most of western Russia, including Saint Petersburg. It is the second-westernmost of the eleven time zones of Russia. It has been set to UTC+03:00 permanently on 26 October 2014; before that date it had been set to UTC+04:00 year-round since 27 March 2011.
UTC+03:00 is an identifier for a time offset from UTC of +03. In areas using this time offset, the time is three hours later than the Coordinated Universal Time (UTC). Following the ISO 8601 standard, a time with this offset would be written as, for example, 2019-02-08T23:36:06+03:00.
UTC+13:00 is an identifier for a +13 hour time offset from UTC.
The time in China follows a single standard time offset of UTC+08:00, despite China spanning five geographical time zones. The official national standard time is called Beijing Time domestically and China Standard Time (CST) internationally. Daylight saving time has not been observed since 1991.
There are eleven time zones in Russia, which currently observe times ranging from UTC+02:00 to UTC+12:00. Daylight saving time is not used in Russia.
UTC+07:20 is an identifier for a time offset from UTC of +07:20.
The Indonesian archipelago geographically stretches across three time zones from UTC+07:00 in Aceh to UTC+09:00 in Western New Guinea. However, the Indonesian government only recognizes three time zones in its territory:
Iran Standard Time (IRST) or Iran Time (IT) is the time zone used in Iran. Iran uses a UTC offset UTC+03:30. IRST is defined by the 52.5 degrees east meridian, the same meridian which defines the Iranian calendar and is the official meridian of Iran.
Europe spans seven primary time zones, excluding summer time offsets. Most European countries use summer time and harmonise their summer time adjustments; see Summer time in Europe for details.
South Korea has one time zone, Korea Standard Time (UTC+09:00), which is abbreviated KST. South Korea does not currently observe daylight saving time, but experimented with it during the 1988 Summer Olympics in Seoul.
As of 2018, daylight saving time (DST) is permanently observed in Morocco, previously time was advanced to UTC+01:00 at 02:00 on the last Sunday of March, and reverted to UTC±00:00, defined as Greenwich Mean Time locally, at 03:00 on the last Sunday of October. This practise was continued through October 2018, after which clocks were permanently advanced. An exception was made during the month of Ramadan during which clocks reverted to UTC+00:00.
Most areas in North America and Europe, and some areas in the Middle East, observe daylight saving time (DST), while most areas of Africa and Asia do not. In South America, most countries in the north of the continent near the equator do not observe DST, while Paraguay does. The practice of observing daylight saving time in Oceania is also mixed, with New Zealand and parts of southeastern Australia observing DST, while most other areas do not.
