Greenwich Mean Time

London is popular for tourists and there are many well known landmarks to visit such as Buckingham Palace, the House of Commons, Tower of London and Big Ben. For an alternative landmark you could take a trip up the Thames and visit the home of GMT (Greenwich Mean Time) since after all this is the place that the time zone for the UK, BBC World Service, Met Office and the Royal Navy originated.

The term GMT originally referred to mean solar time at the Royal Observatory in Greenwich, London. The UK only refers to GMT during the winter as during the summer British Summer Time is use. As the United Kingdom grew and become more of an advanced maritime nation, the mariners kept at least one chronometer on their fob watches set to GMT to calculate their longitude from the Greenwich meridian as this is considered to have longitude zero degrees. GMT was adopted and legally used throughout the island of Great Britain in 1880 and the surrounding islands joined afterwards with Isle of Man (1883), Jersey (1898) and Guernsey (1913). Ireland followed suit in 1916 instead of using Dublin Mean Time.

With Big Ben and then the Greenwich Mean Time in the observatory there is no need to be late or have any excuse to being late again.
