Current time in Al Batinah South, Oman

The governorate follows the same official time as every other part of Oman. Its time-zone abbreviation is GST, and its UTC offset is UTC+4. Oman does not observe daylight saving time, so residents do not move their clocks forward or backward during the year.

This fixed offset makes conversions predictable. Al Batinah South is four hours ahead of London when the United Kingdom is on Greenwich Mean Time, but only three hours ahead when Britain observes summer time. Check the date as well as the location whenever you arrange an international call.

Standard time zone: Gulf Standard Time Time-zone abbreviation: GST UTC offset: UTC+4 Seasonal clock changes: none Same civil time as Muscat and the rest of Oman In Al Batinah South, the clock is steady; it is the sun that keeps changing the appointment.

Cities and local time across the governorate

Rustaq is the administrative centre of Al Batinah South. Other important population centres include Barka, Al Musannah, Nakhal, Al Awabi and Wadi Al Maawil. These places lie between the Al Hajar Mountains and the coast of the Gulf of Oman, but all use one common time.

No time adjustment is needed when travelling between coastal Barka, inland Rustaq or the mountain approaches near Nakhal. A meeting advertised for a particular hour therefore begins at that same clock time throughout the governorate.

Rustaq is a useful reference point for government business, while Barka and Al Musannah are convenient references for the coastal part of the region. Local spellings may vary in English, especially Al Musannah or Al Mussanah, but that has no effect on time-zone searches.

Sunrise and daylight in Al Batinah South

Sunrise depends on the date and the observer’s exact position. Coastal communities and settlements closer to the mountains can record slightly different sunrise times even though their clocks agree. Mountain ridges may also delay the moment when the sun becomes directly visible from a particular street or valley.

Days are longer around the middle of the year and shorter around the end and beginning of the year. For an accurate result, choose the specific town and date rather than applying a single annual sunrise time to the entire governorate.

Select Rustaq, Barka or another nearby locality. Confirm that the displayed zone is UTC+4. Enter the intended calendar date. Distinguish calculated sunrise from the first sunlight visible above local terrain.
