From WordNet (r) 3.0 (2006) [wn]:
coordinated universal time
  1. Greenwich Mean Time updated with leap seconds [syn: coordinated universal time, UTC]
From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
   Coordinated Universal Time
      (UTC, World Time) The standard time common to
      every place in the world.   UTC is derived from {International
      Atomic Time} (TAI) by the addition of a whole number of "leap
      seconds" to synchronise it with {Universal Time} 1 (UT1), thus
      allowing for the eccentricity of the Earth's orbit, the
      rotational axis tilt (23.5 degrees), but still showing the
      Earth's irregular rotation, on which UT1 is based.
      Coordinated Universal Time is expressed using a 24-hour clock
      and uses the {Gregorian calendar}.   It is used in aeroplane
      and ship navigation, where it also sometimes known by the
      military name, "Zulu time".   "Zulu" in the phonetic alphabet
      stands for "Z" which stands for longitude zero.
      UTC was defined by the International Radio Consultative
      Committee ({CCIR}), a predecessor of the {ITU-T}.   CCIR
      Recommendation 460-4, or ITU-T Recommendation X.680 (7/94),
      contains the full definition.
      The language-independent international abbreviation, UTC, is
      neither English nor French.   It means both "Coordinated
      Universal Time" and "Temps Universel Coordonn".
