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 uses a 24-hour system of time notation. 1:00 a.m. in UTC is expressed as 0100, pronounced zero one hundred.. Fifteen minutes after 0100 is expressed as 0115; thirty-eight minutes after 0100 is 0138 (usually pronounced zero one thirty-eight). The time one minute after 0159 is 0200.ne minute later is 0000 (zero hundred), and the start of a new UTC day. To convert UTC to local time, you have to add or subtract hours from it. For persons west of the zero meridian to the international date line (which includes all of North America), hours are subtracted from UTC to convert to local time.
