Before 20th Century, Singapore Local Mean Time was similar with the Straits Settlement, West Malaysia today. By the early 20th Century, Singapore time had been adopted according to the mean time of the 105th Meridien when the Time Ball on Fort canning was completed and operational.
To allow labourers more leisure time after work, by 1920 until 1941, Singapore time was moved 30 minutes forward, not before moving back 10 minutes in 1933.
Such forward backward movement of Singapore time was again in 1942 moved ahead by 1h 30 min when Singapore was formely occupied by the Japanese, which was moved back again in 1945. Finally in 1982, Singapore time moved in sync with West Malaysia when the latter moved in sync with their East.
As such, since 1st January 1982, Singapore’s natural time zone is GMT 8+ instead when it should be seven hours ahead of Greenwich Mean Time (GMT +7).
Chronological adoption of different ‘ Standard Time” in Singapore as a quick reference.
“Standard Time” in Use in Singapore
If astronomers, mathematicians scientists determine the time of day, in Singapore,
the sun would rise at 6am and we can all wake up naturally with the sunlight and start our day fresh. Now, we wake up before sunrise and go to bed later in the night.
This happens from a young age here, so when we grow up, our body clock and nature’s clock are out of sync. Hence, people suffer from sleeplessness and other kinds of diseases.
This also makes people work longer hours, starting early and staying late because the sun has not set. People tend to not leave the office, even at around 6pm, because it is bright outside, even if there is no work.
Being close to the equator, sunset times in Singapore do not vary much.
