Singapore Standard Time (abbreviation: SST;) or Singapore Time (abbreviation: SIN;) is the time zone used in Singapore, 8 hours ahead of UTC (UTC+08: 00).
History
Singapore is situated 103deg 51' 16" East of Greenwich and lies within the UTC+07: 00 time zone. Before 31 May 1905, the local time was UTC+06: 55: 25 ahead of Greenwich Mean Time.
During World War II, when the Japanese occupied Singapore, UTC+09: 00 was used, to follow Japan time, while UTC+07: 20 and UTC+07: 30 were used for daylight saving time. When Peninsular Malaysia moved its standard time 30 minutes ahead from UTC+07: 30 to UTC+08: 00 on 31 December 1981, Singapore shifted too.
The city state started using UTC+08: 00 on 1 January 1982 and the country celebrated New Year' s Day half an hour earlier.
