The zone is two hours ahead of UTC 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 .
The lunar month (as defined by the moon's rotation) is not 28 days but 28.3 days. The year, defined in the Gregorian calendar as 365.2425 days has to be adjusted with leap days and leap seconds. Consequently, these units are now all defined for scientific purposes as multiples of seconds.
One standard day thus went on to become two consecutive equal 12-hour clockfaces in modern clock time. 30 standard days were a standard month, and 12 of those a standard year of 360 days. Some juggling of month lengths to make the 12 months fit the year was still required. Within a day, single hours were unreliable. They came in all sizes.
Due to the large size of the British company rule in Rhodesia, it meant Rhodesia observed three standards of time: UTC+01:30, +2:15 and +2:30; this was problematic for the railway system, so on 1 August 1899 the standard time zones UTC+02:30 was adopted nationwide, [10] consequently resulting in this being the first standard time in Africa.
An apparent solar day can be 20 seconds shorter or 30 seconds longer than a mean solar day. [ 9 ] [ 14 ] Long or short days occur in succession, so the difference builds up until mean time is ahead of apparent time by about 14 minutes near February 6, and behind apparent time by about 16 minutes near November 3.
