Coordinated Universal Time

("UTC" redirects here. For other uses, see UTC (disambiguation).)(This article is about the time standard abbreviated as "UTC". For the time offset between UTC−1 and UTC+1, see UTC±00:00.) Coordinated Universal Time (French: Temps universel coordonné), abbreviated as UTC, is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time at 0° longitude; it does not observe daylight saving time. It is one of several closely related successors to Greenwich Mean Time (GMT). For most purposes, UTC is considered interchangeable with GMT, but GMT is no longer precisely defined by the scientific community.
