Cleveland Abbe
In order to compile his information, Abbe required a time-keeping system that was consistent among the stations. To accomplish this he divided the United States into four standard time zones. He published, in 1879, a paper titled "Report on Standard Time". In 1883, he convinced North American railroad companies to adopt his time-zone system. In 1884, Britain, which had already adopted its own standard time system for England, Scotland, and Wales, helped gather international consent for global time. In time, the American government, influenced in part by his 1879 paper, adopted the time-zone system.
Standard time
In the Netherlands, introduction of the railways made it desirable to create a standard time. On 1 May 1909, or Dutch Time was introduced. Before that, time was measured in different cities and in the east of the country, this was a few minutes later than in the west. In 1909, a national time was introduced which was the same as the local time in Amsterdam, to be precise the exact time of the Wester Tower (Westertoren/4°53'01.95" E). This time was indicated as GMT +0h 19m 32.13s until 17 March 1937, after which it was simplified to GMT+0h20m. This time zone was also known as the "Loenen time" or "Gorinchem time", as this was the exact time in both Loenen and Gorinchem. At noon in Amsterdam, it was 11:40 in London and 12:40 in Berlin.
