History
editUTC 00:20 was used in the Netherlands from 1 May 1909 to 16 May 1940. It was known as Amsterdam Time or Dutch Time.
The exact time zone was GMT 0h 19m 32.13s until 1 July 1937, when it was simplified to GMT 0h 20m. When Germany occupied the Netherlands in World War II, Berlin Time was adopted, and this has been retained ever since.
The reason for the specific offset of 0h 19m 32.13s was that the time zone was centered on the mean solar time of the Westertoren (4° 53' 01.95" E Longitude),[1][2] the tower of the Westerkerk church in Amsterdam.
UTC 00:20 was also used as daylight saving time in the British colony Gold Coast between 1919 and 1942.[3]
