格林尼治平时 Greenwich Mean Time

（重定向自Greenwich Time）
设于英国格林威治皇家天文台大门外的24小时制电子大钟，显示格林威治标准时间。

格林威治标准时间（中国大陆翻译：格林尼治平均时间或格林尼治标准时间，台、港、澳翻译：格林威治标准时间；英语：Greenwich Mean Time，GMT）是指位于英国伦敦郊区的皇家格林威治天文台的标准时间，因为本初子午线被定义为通过那里的经线。

自1924年2月5日开始，格林威治天文台每隔一小时会向全世界发放调时信息。

理论上来说，格林威治标准时间的正午是指当太阳横穿格林威治子午线时（也就是在格林威治上空最高点时）的时间。由于地球在它的椭圆轨道里的运动速度不均匀，这个时刻可能与实际的太阳时有误差，最大误差达16分钟。

Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London. GMT was formerly used as the international civil time standard, now superseded in that function by Coordinated Universal Time (UTC). Today GMT is considered equivalent to UTC for UK civil purposes (but this is not formalized) and for navigation is considered equivalent to UT1 (the modern form of mean solar time at 0° longitude); these two meanings can differ by up to 0.9 s. Consequently, the term GMT should not be used for precise purposes.
