Prior to 1972, this time was called Greenwich Mean Time (GMT) but is now referred to as Coordinated Universal Time or Universal Time Coordinated (UTC). It is a coordinated time scale, maintained by the Bureau International des Poids et Mesures (BIPM). It is also known as Z time or Zulu Time.
UTC and GMT an update. The worldwide standard for coordinated universal time, formerly known as GMT (Greenwich Mean Time), is now abbreviated as UTC (Coordinated Universal Time). Some sources still refer to it as UTC/GMT and some web browsers, e.g. Mozilla Firefox, still display it as GMT. The UTC Time (shown directly below) is the standard time zone upon which all other worldwide time zones are based.
