History

Use in Indonesia

From 1932 through 1942 through Staatsblad no. 412 (1932), and again from 1950 through 1963 through Presidential Instruction no. 152 (1950), Indonesia utilised this time zone in Java, Madura, Bali, and the Indonesian part of Borneo (Kalimantan).

Currently, while Java, Madura, West Kalimantan, and Central Kalimantan use 00, Bali, East Kalimantan (including Nusantara), North Kalimantan, and South Kalimantan use 00.

Use in Peninsular Malaysia and Singapore

UTC+07:30 was also used, initially as daylight saving time, and later as standard time, in Malaya (the Malay peninsula) and Singapore. Between 1941 and 1942 before the Japanese occupation, and from 1945 to 1965 after the occupation Malaya and Singapore used UTC+07:30 as daylight saving time. It was later in 1965 when Singapore decided to declare UTC+07:30 as its standard time.

The Malaysian government announced in December 1981 that it would adjust Peninsular Malaysia’s time by 30 minutes on 1 January 1982 in order to keep common time with East Malaysia. In view of Singapore’s close relations with Malaysia and also to prevent confusion for travellers and businessmen, the Singapore government made a very quick decision to follow suit.

00 is the current time zone for Malaysia and Singapore and this standard time has been in use since 1982.
