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 is the time standard commonly used across the world since 1972. It is used to synchronize time across internet networks. It is also used by meterologists and the aviation industry, and is informally known as Zulu Time to avoid confusion about time zones and daylight saving time.
