What SAST and CST Actually Are
SAST — South Africa Standard Time
Johannesburg, Cape Town, Durban, Pretoria. Standing at UTC+2:00 as written, and the region does not change its clocks, so that offset holds all year. South Africa does not observe daylight saving, so this offset is fixed year-round.
South Africa last used daylight saving during the Second World War and has stayed on a single fixed offset ever since.
CST — Central Standard Time
Chicago, Houston, Dallas, Mexico City, Winnipeg. Standing at UTC-6:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to CST. CST also stands for China Standard Time (UTC+8) and Cuba Standard Time (UTC-5). This page covers the North American one.
Saskatchewan sits inside the Central zone but never changes its clocks, so it matches CST in winter and its neighbors' MDT in summer.
What This Means in Practice
This gap is not fixed
CST changes its clocks and SAST does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.
