Arabia Standard Time in the context of Central Africa Time

Eastern European Time (EET) is one of the names of the 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.

Eastern European Summer Time (EEST) is one of the names of the UTC+03:00 time zone, which is 3 hours ahead of Coordinated Universal Time. It is used as a summer daylight saving time in some European and Middle Eastern countries, which makes it the same as Arabia Standard Time, East Africa Time, and Moscow Time. During the winter periods, Eastern European Time (UTC+02:00) is used.

Since 1996, European Summer Time has been applied from the last Sunday in March to the last Sunday in October. Previously, the rules were not uniform across the European Union.

In Turkey, time is given by UTC+03:00 year-round. This time is also called Turkey Time (TRT). The time at most is the same as in the Moscow Time and Arabia Standard Time zones. TRT was adopted by the Turkish Government on 8 September 2016. It was also in use in Northern Cyprus until it reverted to Eastern European Time (EET) in October 2017.

During some seasons (March–October), the TRT coincides with the Eastern European Summer Time (the daylight-saving version of the Eastern European Time). The IANA time zone identifier for Turkey is Europe/Istanbul.

Egypt Standard Time (EGY) (Arabic: توقيت مصر القياسي Tawqīt Miṣr al-qiyāsiyy) is UTC+02:00, which is equivalent to Eastern European Time, Central Africa Time, South African Standard Time and Central European Summer Time, and is co-linear with neighbouring Libya and Sudan(Winter only). Egypt has used Eastern European Summer Time (UTC+03:00), during the summer periods from 1957 to 2010, 2014 to 2015, and since 2023.

East Africa Time (EAT) is a time zone used in eastern and central Africa, with a standard offset of UTC+03:00 from Coordinated Universal Time (UTC). It is one of the most widely used time zones in Africa, adopted by countries including Kenya, Tanzania, Uganda, Ethiopia, Somalia, and others. EAT does not observe daylight saving time (DST), maintaining a consistent offset year-round due to the region's equatorial proximity, which results in minimal variation in daylight hours. In the IANA time zone database, EAT is represented by the canonical identifier Africa/Nairobi, with aliases such as Africa/Kampala and Africa/Dar_es_Salaam.

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.

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.

Between 2005 and 2008, by decree of President Mahmoud Ahmadinejad, Iran did not observe daylight saving time (DST) (called Iran Daylight Time or IRDT). It was reintroduced from 21 March 2008. On 21 September 2022, Iran abolished DST and now observes standard time year-round.

UTC+04:00 is an identifier for a time offset from UTC of +04:00. In ISO 8601, the associated time would be written as 2019-02-07T23:28:34+04:00. This time is used in:
