About KST

Korea Standard Time (KST) is UTC+9. It is used in South Korea, with no daylight saving.

Korea Standard Time is UTC+9, the same as Japan, and South Korea has had no daylight saving since 1988 when it was used for the Seoul Olympics. The two Koreas briefly differed: the North moved to UTC+8:30 in 2015 and returned to UTC+9 in 2018, which is the only time in modern history the peninsula ran on two clocks.

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 KST nor SAST shifts with the seasons, so this 7-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.
