Following the Japanese occupation, Malaya adopted Tokyo time of GMT+9 on 15 February 1942. Although official appointments were made according to Tokyo time it was common practice to keep two separate times: the pre-Occupation time at home and Tokyo time on personal watches.
At the end of World War II and the return of Malaya to the British, Singapore returned to its pre-war timezone.
Malaysian Standardisation Edit
In 1981, Malaysia decided to standardize the time across its territories to a uniform UTC+08:00. Singapore decided to follow suit, citing business and travel schedules. The change took effect on 1 January 1982, when Singapore moved half an hour forward, creating "Singapore Standard Time" (SST). SST is eight hours ahead of GMT and is synchronized with Hong Kong, Taiwan and Beijing.
