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.
While the former indicates that a date and time value is Coordinated Universal Time (UTC) by assigning DateTimeKind.Utc to its Kind property, the latter assigns the date and time value the UTC time's offset (equal to TimeSpan.Zero).
