What CT and SAST Actually Are
CT — Central 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.
Central Time is the widest US zone by land area, stretching from the Gulf coast to the Canadian border, and it also covers Mexico City.
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.
What This Means in Practice
This gap is not fixed
CT 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.
