South African Standard Time
South African Standard Time
(SAST) is the time zone used by all of South Africa, Botswana
Botswana
as well as Swaziland
Swaziland
and Lesotho. The zone is two hours ahead of UTC
UTC
(UTC+2) 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
Pietermaritzburg
at the correct solar noon point, with Johannesburg and Pretoria
Pretoria
slightly west at 28° E and Durban
Durban
slightly east at 31° E. Thus, most of South Africa's population experience true solar noon at approximately 12:00 daily. The western Northern Cape
Northern Cape
and Western Cape
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+1
UTC+1
but still being in South African Standard Time. Sunrise and sunset are thus relatively late in Cape Town
Cape Town
compared to the rest of the country. To illustrate, daylight hours for South Africa's western and eastern-most major cities:

1 January 1 July

Cape Town 05:38–20:01 07:52–17:48

Durban 04:58–19:00 06:52–17:07

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
South Africa
(NMISA) at Pretoria
Pretoria
and is distributed publicly by an NTP Internet Time service.[1][2] History[edit] Before 8 February 1892, there was no uniformity of time in South Africa and local mean time was in use at the various towns. In 1892, a railway conference was held in Bloemfontein
Bloemfontein
and discussed difficulty of working a railway system, in the absence of a uniform time system. The governments of the Orange Free State, Transvaal and the Cape Colony officially adopted a uniform standard time of Greenwich Mean Time (GMT)+01:30 which was defined as mean time 22.5° east of Greenwich.[3] On 1 March 1903 GMT+02:00 was adopted, which became the current UTC+02:00 when UTC
UTC
replaced GMT for most purposes.[4][5] Prior to 1 March 1903, the Colony of Natal
Colony of Natal
was already using a uniform time supplied by the Natal Observatory. The observatory's local mean time was GMT+1:57. South Africa
South Africa
observed a daylight saving time of GMT+3:00 between 20 September 1942 to 21 March 1943 and 19 September 1943 to 21 March 1944.[6] South African Standard Time
South African Standard Time
is defined as "Coordinated Universal Time plus two hours" ( UTC

+2:00) as defined in South African National Government Gazette No. 40125 of 8 July 2016.[7] See also[edit]
