UTC · UTC+0
GMT stands for Greenwich Mean Time, a fixed UTC+0 offset used by aviation, shipping and computing worldwide, and by the UK in winter. There is no seasonal switch, so GMT means the same thing in January as in July, and the clock above stays UTC+0 every day of the year. Watch out for one trap: the UK itself leaves GMT between late March and late October, when London is an hour ahead on British Summer Time. If you want London's wall clock rather than the GMT standard, use the London page.
