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.
Coordinated Universal Time or UTC is the reference point to determine time zone offsets. UTC corresponds to mean solar time on the Prime or Greenwich Meridian (0Â° longitude). Time zone offsets from UTC range from UTC-12:00 to UTC+14:00. Almost all countries in Europe and North America as well as many other countries observe Daylight Saving Time (DST) and put their clocks an hour forward in the spring and an hour back in the autumn.
