4/11/2024 0 Comments East coast time zone gmtUTC is also known as Zulu time or simply Z.Ĭonversion between time zones can be calculated by adding and subtracting the corresponding offset to UTC. Since then, GMT is no longer a time standard but a time zone, although both share the same current time and are sometimes used incorrectly as synonyms. It is defined as the mean solar time at 0 degrees longitude. The Coordinated Universal Time or UTC was established in 1960 and it is the successor to Greenwich Mean Time. The Royal Observatory established the Greenwich Mean Time (GMT), the solar time at that location (Greenwich, London) as a way of reference to sailors to calculate their current longitude, knowing the difference between the time onboard, which was the solar time at that location, and the Greenwich Mean Time kept by portable timekeepers. So when it is solar noon in Berlin which is 13.4 degrees east, it is about an hour before solar noon in London, located at the same latitude and 0 degrees of longitude. 15 degrees of longitude corresponds to 60 minutes of time. The apparent position of the Sun in the sky is different depending on the location due to the spherical shape of the Earth. Mauritius Time and Seychelles Time are four hours ahead of the UTC (UTC+4) and are used by Mauritius and Seychelles in the Indian Ocean.As each time zone is 1 hour apart, we could expect that in the world there were 24 time zones, however, several time zones are sepa rated by 30 and 45 minutes, so the total number of time zones is 40. EAT is three hours ahead of the UTC (UTC+3), making it the same as Arabia Standard Time, Moscow Time, and Eastern European Summer Time. Most of these countries are located on or around the equator. East Africa Time ZoneĮast Africa Time (EAT), also known as Eastern Africa Time is observed by nine Eastern Africa countries, including Kenya, Uganda, Tanzania, Ethiopia, Madagascar, and Somalia. Some of these countries are Egypt, South Africa, Botswana, South Sudan, Zimbabwe, Namibia, and Rwanda. It is observed by some Southern, Central, and Northern African countries, laying on the tropical and equatorial regions. Central Africa Time ZoneĬentral Africa Time (CAT) is two hours ahead of Coordinated Universal Time (UTC+2) during standard time, making it the same as Egypt Standard Time, South Africa Standard Time, and Central European Standard Time. Some of these countries include Tunisia, the DRC, Cameroon, Chad, Benin, and the Congo. This time zone is mainly observed by 15 African countries, located mainly in the tropical region. West Africa Time (WAT) is one hour ahead of UTC (UTC+1), making it the same as Western European Sumer Time (WEST) during summer and Central European Time (CET) in winter. Morocco uses WET in winter and Western European Standard Time in the summer. Greenwich Mean Time is observed by West African countries, including Nigeria, Ghana, Ivory Coast, Burkina Faso, Senegal, Liberia, and Togo. These three time zones do not have offset time from the UTC, meaning they are not ahead or behind the UTC. The Greenwich Mean Time (GMT/UTC) is also observed as Western Sahara Time Zone (WST) and corresponds to Western European Time Zone (WET). Other time zones with similar offset as CVT are East Greenland Time and November Time Zone. ![]() ![]() This time zone is one hour behind the Coordinated Universal Time (UTC-1). Cape Verde Time ZoneĬape Verde Time (CVT) is a time zone observed only in Cape Verde, an Atlantic island off Africa’s west coast. The different shades of color represent the different time zone areas. No African country observes Daylight Saving Time except Morocco. The six African time zones are Mauritius and Seychelles Time (UTC/GMT+4), East Africa Time (UTC/GMT+3), Central Africa Time (UTC/GMT+2), West Africa Time (UTC/GMT+1), Greenwich Mean Time (UTC/GMT), and Cape Verde Time (UTC-1). However, it uses 13 names to describe its standard time zones. Africa observes six standard time zones, having an offset range of between UTC-1 and UTC+4. It is bordered to the north by Europe and Asia, collectively known as Eurasia, and uses some time zones used in Europe. Africa is the world’s second-largest continent, after Asia, spanning 30.4 million km 2.
