About UTC

UTC is the abbreviation for Coordinated Universal Time, a time zone offset of UTC. It applies in Global reference.

The primary time standard the world sets its clocks by. It never changes for daylight saving. UTC replaced GMT as the technical standard, though the two are the same to the second for everyday use.

Time-zone abbreviations are convenient but not unique or official — several codes are shared by more than one zone. When precision matters, use the underlying IANA zone name (for example Etc/UTC) or the UTC offset UTC instead.
