UTC+0:20时区比协调世界时快20分钟，曾在1909年至1940年间使用于荷兰，也被称为阿姆斯特丹时间或荷兰时间。

其实际时间为格林威治标准时间+0小时19分32.13秒，直到1937年3月17日才被简化成+0小时20分。荷兰在第二次世界大战被德国占领时，采用的是柏林时间（UTC+1），沿用至今。

UTC+00:20 is an identifier for a time offset from UTC of +00:20.

UTC+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 timezone was GMT +0h 19m 32.13s until March 17, 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.
