West Africa Time, or WAT, is a time zone used in west-central Africa.West Africa Time is one hour ahead of Coordinated Universal Time (UTC+01:00), which makes it the same as Central European Time (CET) during winter, or Western European Summer Time (WEST) / British Summer Time (BST) during the summer.
As most of this time zone is in the tropical region, there is little change in day length throughout the year, so daylight saving time is not observed.
West Africa Time is the time zone for the following countries:
Countries west of Benin (except Morocco and Western Sahara) are in the UTC±0 time zone. Civil time in most of those countries is defined with reference to Greenwich Mean Time [ citation needed ] (now an alias for UTC±0, rather than an independent reference).
Western European Summer Time is a summer daylight saving time scheme, 1 hour ahead of Greenwich Mean Time and Coordinated Universal Time. It is used in:
Swatch Internet Time is a decimal time concept introduced in 1998 by the Swatch corporation as part of their marketing campaign for their line of "Beat" watches.
The North American Central Time Zone (CT) is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean.
The Alaska Time Zone observes standard time by subtracting nine hours from Coordinated Universal Time (UTC−09:00). During daylight saving time its time offset is eight hours (UTC−08:00). The clock time in this zone is based on mean solar time at the 135th meridian west of the Greenwich Observatory.
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 and under other names like Berlin Time, Warsaw Time, Paris Time or Rome Time.
Western European Time is a time zone covering parts of western Europe and consists of countries using UTC±00:00. It is one of the three standard time zones in the European Union along with Central European Time and Eastern European Time.
Summer time in Europe 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, with a view to making the most efficient use of seasonal daylight. It corresponds to the notion and practice of daylight saving time (DST) to be found in many other parts of the world.
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.
Central European Summer Time (CEST), sometimes referred to 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 during the other part of the year. It corresponds to UTC+02:00, which makes it the same as Eastern European Time, Central Africa Time, South African Standard Time and Kaliningrad Time in Russia.
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 without DST since 26 October 2014; before that date it had been set to UTC+04:00 year-round on 27 March 2011.
UTC+01:00 is an identifier for a time offset from UTC of +01:00. In ISO 8601, the associated time would be written as 2019-02-07T23:28:34+01:00. This time is used in:
The UTC offset is the difference in hours and minutes from Coordinated Universal Time (UTC) for a particular place and date. It is generally shown in the format ±[hh]:[mm], ±[hh][mm], or ±[hh]. So if the time being described is one hour ahead of UTC, the UTC offset would be "+01:00", "+0100", or simply "+01".
The time zone in Germany is Central European Time and Central European Summer Time. Daylight saving time is observed from the last Sunday in March to the last Sunday in October. The doubled hour during the switch back to standard time is named 2A and 2B.
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, Eastern European Time, Kaliningrad Time and Central European Summer Time.
East Africa Time, or EAT, is a time zone used in eastern Africa. The time zone is three hours ahead of UTC (UTC+03:00), which is the same as Moscow Time, Arabia Standard Time, Further-eastern European Time and Eastern European Summer Time.
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.
Time in Ukraine is defined as UTC+02:00 and in summer as UTC+03:00. Part of Eastern European Time, it is locally referred to as Kyiv Time. The change for the summer time takes place in the last week of March at 03:00, when the time is changed by an hour ahead, and the last week of October at 04:00, when the time changes an hour back. In this way, the clocks in Ukraine are always one hour ahead of those in central Europe.
The only African countries and regions that use daylight saving time are:
Winter time is the practice of shifting the clock back during winter months, usually −1 hour. It is a form of daylight saving time which is the opposite compensation to the summer time. However, while summer time is widely applied, use of winter time has been and is very rare.
Namibia since September 2017 is in the Central Africa Time zone at UTC+02:00, congruous with South African Standard Time.
