1. greenwich mean time

   Greenwich Mean Time (GMT) is a time system originally referring to mean solar time at the Royal Observatory located in Greenwich, London, which has long been the location of the internationally recognized prime meridian (0-degree longitude). GMT is used as the base reference for time zones worldwide. It was once the international standard of civil timekeeping but has been largely replaced by Coordinated Universal Time (UTC). However, in some contexts and regions, GMT still serves as a synonym for time zone of UTC+0.

1. Greenwich Mean Time

   Greenwich Mean Time originally referred to mean solar time at the Royal Observatory in Greenwich, London, which later became adopted as a global time standard. It is arguably the same as Coordinated Universal Time, and when this is viewed as a time zone, the name Greenwich Mean Time is especially used by bodies connected with the United Kingdom, such as the BBC World Service, the Royal Navy, the Met Office and others particularly in Arab countries, such as the Middle East Broadcasting Center and OSN. It is the term in common use in the United Kingdom and countries of the Commonwealth, including Australia, South Africa, India, Pakistan and Malaysia, and many other countries in the Old World. Before the introduction of UTC on 1 January 1972, Greenwich Mean Time was the same as Universal Time, a standard astronomical concept used in many technical fields. Astronomers no longer use the term "Greenwich Mean Time". In the United Kingdom, GMT is the official time during winter; during summer British Summer Time is used. GMT is the same as Western European Time. Noon Greenwich Mean Time is rarely the exact moment when the sun crosses the Greenwich meridian and reaches its highest point in the sky there, because of Earth's uneven speed in its elliptic orbit and its axial tilt. This event may be up to 16 minutes away from noon GMT, a discrepancy calculated by the equation of time. Noon is the annual average time of this event, prompting the inclusion of "mean" in "Greenwich Mean Time".
