About Jamestown time
Jamestown keeps one clock.
On this remote volcanic speck in the South Atlantic, the pace of life in Jamestown—the capital of Saint Helena, Ascension and Tristan da Cunha—moves by unclocked island time that just happens to align perfectly with Greenwich Mean Time. There’s no daylight saving to worry about or quirky UTC offsets: if your team runs on GMT, syncing with Jamestown workers is refreshingly seamless, even if dinner tables and daily routines look a bit different from your home office.
