Singapore Standard Time

Singapore Standard Time

Singapore uses a time zone eight hours in advance of UTC, (UTC+8). It is known as Singapore Standard Time or SST, and is the same as Australian Western Standard Time, Central Indonesia Time, Malaysian Standard Time, Philippine Standard Time, Chinese Standard Time, Hong Kong Time and Macau Standard Time.

History

According to longitude, Singapore is 103° 51' 16" East of Greenwich, and lies within the UTC+7 time zone. Before May 31, 1905, the local time was 6:55:25 ahead of Greenwich Mean Time. During the Japanese occupation of Singapore, UTC+9 was used. As daylight saving time and were used. When Peninsular Malaysia moved its standard time 30 minutes ahead of UTC+7:30 to UTC+8:00 in 1981, Singapore followed suit for economic and political reasons. The city state started using UTC+8 on 1 January 1982, and the country celebrated New Year's Day half an hour earlier.

Singapore Time Server

SPRING Singapore maintains caesium atomic clocks which are aggregrated by Bureau International des Poids et Measures. This time is available to the public through a time server. The server supports Daytime Protocol, Time Protocol and Network Time Protocol and is accessible through the domain nets.org.sg. It is claimed that Singapore Standard Time is always accurate to 100 nanoseconds from UTC [http://www.singaporestandardtime.org.sg/faq.htm#10 SST FAQ Q.10] ] . It appears that the public is welcome to use the server. [http://www.singaporestandardtime.org.sg/nets_home.htm SST Network Time Service] ]
