Singapore Time
time zone

Singapore Time (SGT), also known as Singapore Standard Time (SST), is used in Singapore and is 8 hours ahead of Coordinated Universal Time (UTC+08:00). Singapore does not observe daylight saving time.
History
As part of the Straits Settlements, Singapore originally adopted the Malayan Time, which was GMT+07:30 in 1941. During the Japanese occupation, Singapore (known as Syonan-to) adopted the Tokyo Standard Time of GMT+09:00 on 15 February 1942. At the end of World War II and the return of the Straits Settlements to the British, Singapore reverted to its pre-war time zone.
Daylight saving time in Singapore
Although Singapore does not currently observe daylight saving time in the traditional sense due to its tropical location, a form of daylight saving time, using a 20-minute offset, was introduced on an annual basis by the Legislative Council of the Straits Settlements in 1933.
On 2 July 1920, a bill was intituled as Daylight Saving Ordinance, 1920. It is to introduce a 30-minutes offset or seven and a half hour in advance of Greenwich mean time. The bill was read for the first time on 5 July 1920 but was later abandoned.
In 1932, Sir Arnold Percy Robinson raised the idea of 20-minute offset after an earlier attempt was abandoned in 1920 which was first proposed by Sir Laurence Guillemard for a 30-minute offset.

Why this record matters
“Singapore Time” is worth following because a concise public description often conceals a longer documentary argument. Here, Singapore, Time and time provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q3244578. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1941, 1942, 1933 and 1920.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
