What TRT and CT Actually Are
TRT — Turkey Time
Istanbul, Ankara, İzmir. Standing at UTC+3:00 as written, and the region does not change its clocks, so that offset holds all year. Turkey moved to permanent UTC+3 in 2016 and no longer changes its clocks.
Turkey abandoned clock changes in 2016 by remaining permanently on summer time, so it is now an hour ahead of its Greek and Bulgarian neighbors all year.
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.
What This Means in Practice
This gap is not fixed
CT changes its clocks and TRT 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.
