Jamestown, Saint Helena: Jamestown is the capital city of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, located on the island of Saint Helena in the South Atlantic Ocean. It is also the historic main settlement of the island and is on its north-western coast. Before the development of the port at Rupert's Bay, it was the island's only port and the centre of the island's road and communications network. It was founded when colonists from the English East India Company settled on the island in 1659 and was briefly occupied by the Dutch East India Company in 1673 before being recaptured. Many of the buildings built by the East India Company in the 18th century survive and give the town its distinctive Georgian flavour.
Does not observe daylight saving time. The UTC offset (+00:00) is constant year-round.
Jamestown is listed in the dataset snapshot as aligned with UTC (offset +00:00). 1 hour behind London, 9 hours behind Tokyo.
Geographically at longitude -5.72°, Jamestown's mean solar noon falls about 23 minutes after civil 12:00 under the year-round civil offset — local sunrise and sunset run later on the clock than they would on true solar time.
Jamestown sits at 15.92°S, in the southern tropics, so the sun passes nearly overhead twice a year and the longest-to-shortest day swing stays under about ninety minutes.

Capital status
National capital of St. Helena
Jamestown is the capital of Saint Helena, a British Overseas Territory in the South Atlantic, set in a narrow valley between steep volcanic ridges. The town is the island's administrative and historic port centre, while Saint Helena Airport opened in 2016 on the eastern side of the island and changed access patterns that had previously depended almost entirely on ship links. Saint Helena uses Greenwich Mean Time (UTC+0) year-round with no daylight saving. The page is useful because its clock aligns with UTC while its travel logistics are distinctly South Atlantic.
