History

Liberia first adopted the UTC offset -0:43:08 (called Liberia Mean Time; LMT) as it was the geographical central meridian on which the capital Monrovia was located.[5] The time zone was renamed to Monrovia Mean Time in 1882.[5] In March 1919, the offset was redefined forward by 1 minute and 22 seconds to -0:44:30.[6][7] Liberia adopted Greenwich Mean Time (GMT; UTC+00:00) on 7 January 1972.[8]
