The history of standard time in the United States began November 18, 1883 when American and Canadian railroads instituted standard time in time zones. Before then, time of day was a local matter, and most cities and towns used some form of local solar time, maintained by some well-known clock (for example, on a church steeple or in a jeweler's window). The new standard time system was not immediately embraced by all.
The Great Western Railway (GWR) was a British railway company that linked London with the south-west and west ofEngland and most of Wales. It was founded in 1833, received its enabling Act of Parliament in 1835, and ran its first trains in 1838. It was engineered by Isambard Kingdom Brunel, who chose a broad gauge of 7 ft 0 1⁄4 in (2,140 mm), but from 1854, a series of amalgamations saw it also operate 4 ft 8 1⁄2 in (1,435 mm) standard-gauge trains; the last broad-gauge services were operated in 1892. The GWR was the only company to keep its identity through the Railways Act 1921, which amalgamated it with the remaining independent railways within its territory, and it was finally wound up at the end of 1947 when it was nationalized and became the Western Region of British Railways.
Greenwich Mean Time (GMT) is a time system originally referring 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 (UTC), 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, as well as many other countries in the Old World.
The islands of Great Britain and Ireland used Local Mean Time until railway timetabling gradually established the two standards of Greenwich Mean Time and Dublin Mean Time (UTC-00:25, no longer used). These were officially adopted under the Statutes (Definition of Time) Act 1880 (43 & 44 Vict.). By 1916, Greenwich Mean Time was introduced to Ireland.
