Abbreviation disambiguation
GMT is equivalent to UTC for everyday use. In the UK it also refers to the winter (non-daylight-saving) time; in summer the UK moves to BST (UTC+1).
On Clockjumper, ET refers to the Eastern Time zone of the United States and Canada. ET is an umbrella name rather than a fixed offset: it means EST (UTC−5) in winter and EDT (UTC−4) in summer, and these pages show whichever is currently in force.
