South Africa runs at +02:00
The zone is Africa/Johannesburg. Every window on this page is worked out from that offset rather than a rule of thumb, so the times shown are the ones that actually apply to South Africa.

South Africa stays on +02:00 all year. The windows below only move when the caller's own country changes its clocks, not when South Africa does.
