What is UTC?

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. It has an offset of +00:00 and never observes daylight saving time. All other timezones are defined as a positive or negative offset from UTC.

UTC vs GMT

UTC and GMT (Greenwich Mean Time) display the same time for everyday purposes. The difference is technical: GMT is based on Earth's mean solar rotation, while UTC is maintained by atomic clocks. In programming, UTC is the correct term — JavaScript's toUTCString() and HTTP Date headers both output UTC even though they say 'GMT'.
