'Greenwich Mean cartridge clip (GMT) is a m system originally referring to pissed solar precondition at the Royal lookout station in Greenwich, London, which later became adopted as a global quantify stock. It is arguably the similar as Coordinated customary cartridge clip (coordinated universal time) and when this is viewed as a time zone the name Greenwich Mean measure is especially used by bodies connected with the joined Kingdom, such as the BBC human Service,[1] the Royal Navy, the Met Office and others particularly in Arab countries, such as the Middle eastside Broadcasting Center and OSN.It is the term in common use in the United Kingdom and countries of the Commonwealth, including Australia, South Africa, Nigeria, India and Malaysia, as surface as many other countries in the Old World.
