Definitions
| Type | Definition | Sources |
|---|---|---|
| Noun | A high precision atomic time standard with uniform seconds defined by International Time and leap seconds announced at regular internals to compensate for the earth’s slowing rotation and other discrepancies. Leap seconds allow UTC to closely track Universal Time, a time standard based not on the uniform passage of seconds, but on the Earth’s angular rotation. Time zones around the world are expressed as positive or negative offsets from UTC. Local time is UTC plus the time zone offset for that location, plus an offset (typically +1) for daylight savings, if in effect. As the zero point reference, UTC is also referred to as Zulu time (Z).
