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 EAT
East Africa Time (EAT) is UTC+3. It is used in Kenya, Tanzania, Ethiopia, Uganda and Somalia.
East Africa Time is UTC+3 and fixed. Nairobi, Addis Ababa and Dar es Salaam all keep it. Ethiopia additionally uses a clock that counts from dawn rather than midnight for everyday purposes, six hours off the international one, so a time given locally in Addis may need converting twice rather than once.
Does this gap change with the seasons?
Neither KST nor EAT 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.
