Greenwich Mean Time is UTC+00:00. It is the time the United Kingdom keeps in winter, and it is frequently used as a loose synonym for UTC.

UTC offset: +00:00
Daylight saving: Never changesSame offset all year

GMT is often used loosely to mean UTC. They are the same clock reading, but GMT is also the name of the United Kingdom’s winter time — and the UK is not on GMT in summer.
