Time zone names

The following names and abbreviations are from the Sumatera, Inc. page cited below.

Time    Abbrev   Name                     English equivalent
UTC+7   WIB      Waktu Indonesia Barat    Western Indonesia Standard Time
UTC+8   WITA     Waktu Indonesia Tengah   Central Indonesia Standard Time
UTC+9   WIT      Waktu Indonesia Timur    Eastern Indonesia Standard Time

The following names and abbreviations for Indonesian time zones come from the tz database. They were created by a contributor. Don't assume that these names, or anything like them, have ever been used officially in Indonesia.

The western zone was called Jakarta Mean Time (JMT) from 1924 to 1932, and Java Time (JAVT) thereafter.

The central zone was called Macassar Mean Time (MMT) from 1932 to 1942, and Borneo Time (BORT) thereafter. (Note: the name of the city of Macassar was changed to Ujung Pandang around 1970.)

The eastern zone was called Jayapura Time (JAYT) from 1944 onward.
UTC+9, as used during World War II, was called JST.

UTC+9:30, as used in the eastern zone from 1944 to 1963, was called CST. There is no indication what this stood for.
