TZDB's current data matches those URLs. For example, the command "zdump -V -c 1910,2026 Africa/Johannesburg" outputs:

South Africa has Daylight Saving Time every year from September to April at every first Sunday of September at UTC/GMT+2 South Africa Standard Time from 00:00 to 01:00 South African Summer Time UTC/GMT+3 and it ends at every last Sunday of April at 01:00 to 0:00 back to South Africa Standard Time UTC/GMT+2
Thanks, but this doesn't match either TZDB or timeanddate.com; do you have a source for this?
