About SGT
Singapore Time (SGT) is UTC+8. It is used in Singapore and Malaysia.
Singapore Time is UTC+8 with no daylight saving. The offset is a historical curiosity: Singapore sits at about 104°E, which is geographically UTC+7, and moved to +8 in 1982 to align with Malaysia and Hong Kong for trade. The result is that the sun is at its highest around 1pm rather than noon, and sunrise is late all year.
About SAST
South Africa Standard Time (SAST) is UTC+2. It is used in South Africa, Lesotho and Eswatini.
South Africa Standard Time is UTC+2 with no daylight saving, unchanged since 1903 apart from two wartime years. The whole country keeps it, and so do Lesotho and Eswatini. Against the UK it is two hours ahead in winter and one in summer, which is the shift that catches London–Johannesburg standing calls every March and October.
Does this gap change with the seasons?
Neither SGT nor SAST shifts with the seasons, so this 6-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.
This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
