Is SAST ahead of or behind KST?
SAST is behind KST by 7 hours: when it is 12:00 pm in South Africa, it is 7:00 pm in Korea. Neither South Africa Standard Time nor Korea Standard Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
South Africa Standard Time covers Johannesburg, Cape Town and Durban. Korea Standard Time covers Seoul and South Korea. The identifiers behind them are Africa/Johannesburg and Asia/Seoul, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
