The Time Zones of the UK Overseas Territories
The UK has one time zone at home, but its territories across the world use many different clocks.
Same as the UK
Jersey, Guernsey and the Isle of Man are Crown Dependencies, and keep UK time. St Helena, Ascension and Tristan da Cunha use GMT all year, so they match the UK in winter and are one hour behind in summer.
Different from the UK
Gibraltar uses Central European Time and is always one hour ahead. In the Caribbean, Bermuda is on Atlantic Time with US daylight saving, the Cayman Islands use Eastern Standard Time all year, and the British Virgin Islands use Atlantic Standard Time all year. The Turks and Caicos follow Eastern Time with daylight saving. The Falkland Islands use UTC-3 all year.
Because only some of them change their clocks, and not on UK dates, the gaps with London shift at different times of year.
