London uses Greenwich Mean Time (GMT, UTC+0) in winter and British Summer Time (BST, UTC+1) in summer. The UK clocks go forward one hour on the last Sunday of March and back on the last Sunday of October. GMT takes its name from the Royal Observatory in Greenwich, east London — the historical origin of UTC-based world time.
