Cape Verde Time

Cape Verde Time (CVT) is a time zone used by the Atlantic island nation of Cape Verde. The zone is one hour behind UTC (UTC-01:00).

Daylight saving time is not observed in this time zone.

Central Africa Time

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 (although the latter area uses Eastern European Summer Time (UTC+3) most of the year)

As this time zone is in the equatorial and tropical regions, there is little change in day length throughout the year, and so daylight saving time is not observed.

Central Africa Time is used by the following countries:

Burundi

Botswana

Egypt (observes Eastern European Time)

Democratic Republic of the Congo (eastern)

Libya

Malawi

Mozambique

Namibia

Rwanda

Sudan

Zambia

ZimbabweThe following countries use South African Standard Time instead of Central Africa Time:

Lesotho

South Africa

Eswatini

Central European Time

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.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).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.

East Africa 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 Arabia Standard Time, Further-eastern European Time, Moscow Time and Eastern European Summer Time.As this Time Zone is predominantly in the equatorial region, there is no significant change in day length throughout the year and so daylight saving time is not observed.East Africa Time is used by the following countries:

Comoros

Djibouti

Eritrea

Ethiopia

Kenya

Madagascar

Somalia

South Sudan

Tanzania

Uganda

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.

A number of African countries use UTC+02:00 all year long, where it is called Central Africa Time (CAT), although Egypt and Libya also use the term Eastern European Time.

Greenwich Mean Time

Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London, reckoned from midnight. At different times in the past, it has been calculated in different ways, including being calculated from noon; as a consequence, it cannot be used to specify a precise time unless a context is given.

English speakers often use GMT as a synonym for Coordinated Universal Time (UTC). For navigation, it is considered equivalent to UT1 (the modern form of mean solar time at 0° longitude); but this meaning can differ from UTC by up to 0.9 s. The term GMT should not thus be used for technical purposes.Because of Earth's uneven speed in its elliptical orbit and its axial tilt, noon (12:00:00) GMT is rarely the exact moment the sun crosses the Greenwich meridian and reaches its highest point in the sky there. This event may occur up to 16 minutes before or after noon GMT, a discrepancy calculated by the equation of time. Noon GMT is the annual average (i.e. "mean") moment of this event, which accounts for the word "mean" in "Greenwich Mean Time".

Originally, astronomers considered a GMT day to start at noon, while for almost everyone else it started at midnight. To avoid confusion, the name Universal Time was introduced to denote GMT as counted from midnight. Astronomers preferred the old convention to simplify their observational data, so that each night was logged under a single calendar date. Today Universal Time usually refers to UTC or UT1.The term "GMT" is especially used by bodies connected with the United Kingdom, such as the BBC World Service, the Royal Navy, the Met Office and others particularly in Arab countries, such as the Middle East Broadcasting Centre and OSN. It is a term commonly used in the United Kingdom and countries of the Commonwealth, including Australia, New Zealand, South Africa, India, Pakistan, Bangladesh and Malaysia; and in many other countries of the Eastern Hemisphere.

List of time zone abbreviations

This is a list of time zone abbreviations.

List of time zones by country

This is a list representing time zones by country. Countries are ranked by total number of time zones on their territory. Time zones of a country include that of dependent territories (except Antarctic claims). France, including its overseas territories, has the most time zones with 12. Many countries have daylight saving time, one added hour during the local summer, but this list does not include that information. The UTC offset in the list is not valid in practice during daylight saving time.

Mauritius Time

Mauritius Time, or MUT, is a time zone used by the Indian Ocean island nation of Mauritius. The zone is four hours ahead of UTC (UTC+04:00).

Daylight saving time was used in 2008. Clocks were put forward to UTC+05:00 on October 26, 2008 and put back to standard time on March 29, 2009 at 3 AM local daylight time.

The time change is no longer applied.

South African Standard Time

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.

The western Northern Cape and Western Cape differ, however. Everywhere on land west of 22°30′ E effectively experiences year-round daylight saving time because of its location in true UTC+01:00 but still being in South African Standard Time. Sunrise and sunset are thus relatively late in Cape Town, compared to the rest of the country.

To illustrate, daylight hours for South Africa's western and eastern-most major cities:

The South African National Time Standard, or 'SA Time' Master Clock, is maintained at the Time and Frequency Laboratory of the National Metrology Institute of South Africa (NMISA) at Pretoria and is distributed publicly by an NTP Internet Time service.

Time in Algeria

Algeria Standard Time or DPRA Standard Time is the time zone for the Algeria. It is 1 hours ahead of GMT/UTC (UTC+01:00) and is co-linear with neighboring Tunisia.

Time in Ethiopia

The time zone in Ethiopia is East Africa Time (EAT) (UTC+03). The IANA time zone database identifier is "Africa/Addis Ababa." Ethiopia does not observe daylight saving time. Almost all Ethiopians use a 12-hour clock system. The daytime cycle begins at dawn 12:00 (6:00:00 AM EAT) and ends at dusk 11:59:59 (5:59:59 PM EAT).

The night time cycle begins at dusk 12:00 (6:00:00 PM EAT) and ends at dawn 11:59:59 (5:59:59 AM EAT).

The convention is that the day begins at 1:00 o'clock in the mornng 12 hour cycle (7:00 AM EAT) rather than midnight (12:00 AM EAT). The current time convention persists despite inroads of international norms.

West Africa 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 (GMT; equivalent to UTC with no offset). 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.

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 used by the following countries:

Algeria (as Central European Time)

Angola

Benin

Chad

Cameroon

Central African Republic

Democratic Republic of the Congo (western side only)

Equatorial Guinea

Gabon

Morocco (as Greenwich Mean Time + 1 hour)

Niger

Nigeria

Republic of the Congo

Tunisia (as Central European Time)
