UTC+03:00 is an identifier for a time offset from UTC of +03. In ISO 8601 the associated time would be written as 2011-09-09T07:04:46+03:00 . This time is used in:

As standard time (all year round)

East Africa Time

Kaliningrad Time

Arabia Standard Time

Arabia Standard Time, or AST, is used by some countries in the Middle East. As this time zone is predominantly in the equatorial region, there is no significant change in day length throughout the year, so daylight saving time is not observed. Arabia Standard Time is used by the following countries:

Notes:

  1. The westernmost point at which UTC+03 with no DST is applied is the Russian town of Baltiysk, in the Kaliningrad Oblast, at 19°55′E. Before 27 March 2011, it was the westernmost point of Sudan, in the West Darfur state, at the border with Chad; Geneina, the capital of West Darfur, located very close to that point, has a longitude of 22°27' E.
  2. The easternmost point at which UTC+03 with no DST is applied is actually the easternmost point of Saudi Arabia, in the Eastern Province, at the border with Oman, with a longitude of roughly 55°20' E.

As standard time (Northern Hemisphere winter only)

Formerly Moscow Time, before 27 March 2011; now UTC+4.

As daylight saving time (Northern Hemisphere summer only)

Eastern European Summer Time - Territories observing European Union DST rules

Middle East - observing various DST rules

Observing Russian DST rules

Notes

  1. The westernmost point at which UTC+03 with DST is applied is actually the westernmost point of contiguous Russia, near Lavry, Pskov Oblast (27°19' E). During the summer the time employed there (corresponding to 60°E) is 33°41' E of physical time, i.e. roughly 2 hours and 14 minutes ahead of physical time, making for the largest discrepancy between time used and physical time for UTC+3 with DST. This actually the largest discrepancy overall for UTC+03 even if UTC+03 with no DST is included.
  2. The easternmost point at which UTC+03 with DST is applied is Cape Zhelaniya, Severny Island, Novaya Zemlya, Russia (69°06' E). During the winter the time employed there (corresponding to 45°E) is 24°06' W of physical time, i.e. roughly 1 hour and 36 minutes behind physical time, making for the largest discrepancy between time used and physical time for UTC+3 with DST for that time of the year, but not overall (see note 1 above).
  3. On February 8, 2011, Russian President Dmitry Medvedev issued a decree cancelling DST in Russia. Under the decree, all clocks in Russia will advance one hour on March 27, 2011, but will not change back the following October, effectively making Kaliningrad Time UTC+03 permanently, and Moscow Time UTC+04 permanently.
