South African Standard Time

South African Standard Time (SAST) is the time zone used by all of South Africa as well as Eswatini and Lesotho. The zone is two hours ahead of UTC (UTC+02:00) and is the same as Central Africa Time. Daylight saving time is not observed in either time zone. Solar noon in this time zone occurs at 30° E in SAST, effectively making Pietermaritzburg at the correct solar noon point, with Johannesburg and Pretoria slightly west at 28° E and Durban slightly east at 31° E. Thus, most of South Africa's population experience true solar noon at approximately 12:00 daily.

Time zones of Africa:
 -01:00  Cape Verde Time[a]
 ±00:00  Greenwich Mean Time
 +01:00 
 +02:00 
 +03:00  East Africa Time
 +04:00 
a The islands of Cape Verde are to the west of the African mainland.
b Mauritius and the Seychelles are to the east and north-east of Madagascar respectively.

The western Northern Cape and Western Cape differ, however. Everywhere on land west of 22°30′ E effectively experiences year-round daylight saving time because of its location in true UTC+01:00 but still being in South African Standard Time. Sunrise and sunset are thus relatively late in Cape Town, compared to the rest of the country.

To illustrate, daylight hours for South Africa's western and easternmost major cities:

The South African National Time Standard, or 'SA Time' Master Clock, is maintained at the Time and Frequency Laboratory of the National Metrology Institute of South Africa (NMISA) at Pretoria and is distributed publicly by an NTP Internet Time service.[1][2]
