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. 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 west ...

Time Zone
A time zone is an area which observes a uniform standard time for legal, Commerce, commercial and social purposes. Time zones tend to follow the boundaries between Country, countries and their Administrative division, subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time. Each time zone is defined by a standard offset from Coordinated Universal Time (UTC). The offsets range from UTC−12:00 to UTC+14:00, and are usually a whole number of hours, but a few zones are offset by an additional 30 or 45 minutes, such as in Indian Standard Time, India and Nepal Time, Nepal. Some areas in a time zone may use a different offset for part of the year, typically one hour ahead during spring (season), spring and summer, a practice known as daylight saving time (DST). List of UTC offsets In the table below, the locations that use daylight saving time (DST) are listed in their UTC offset when DST is ' ...

Western Cape
The Western Cape ( ; , ) is a provinces of South Africa, province of South Africa, situated on the south-western coast of the country. It is the List of South African provinces by area, fourth largest of the nine provinces with an area of , and List of South African provinces by population, the third most populous, with an estimated 7 million inhabitants in 2020. About two-thirds of these inhabitants live in the metropolitan area of Cape Town, which is also the provincial capital. The Western Cape was created in 1994 from part of the former Cape Province. The two largest cities are Cape Town and George, Western Cape, George. Geography The Western Cape is roughly L-shaped, extending north and east from the Cape of Good Hope, in the southwestern corner of South Africa. It stretches about northwards along the Atlantic coast and about eastwards along the South African south coast (Southern Indian Ocean). It is bordered on the north by the Northern Cape and on the east by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time Zones
Time is the continuous progression of existence that occurs in an apparently irreversible succession from the past, through the present, and into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events (or the intervals between them), and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions. Time is one of the seven fundamental physical quantities in both the International System of Units (SI) and International System of Quantities. The SI base unit of time is the second, which is defined by measuring the electronic transition frequency of caesium atoms. General relativity is the primary framework for understanding how spacetime works. Through advances in both theoretical and experimental investigations of spacetime, it has been shown that time can be distorted and dilated, particula ...

Noon Gun
The Noon Gun has been a historic time signal in Cape Town, South Africa, since 1806. It consists of a pair of black powder Dutch naval guns, fired alternatingly with one serving as a backup. The guns are situated on Signal Hill, close to the centre of the city. The sight seeing point is officially permanently closed, and public entrance is unattainable. A similar tradition exists in different other locations around the world, including in Nice (France), Hong Kong and at both Québec citadel and Halifax citadel (Canada). History The settlement at the Cape of Good Hope was founded by the Dutch in 1652 and the signal guns were originally part of the regular artillery at the Imhoff Battery at the Castle in Cape Town. The guns, which are still in use today, are 18 pounder smooth bore muzzle loading guns, and were designed by captain Thomas Blomfield in 1786. They were cast by Walker & Co. in early 1794, and proof fired at Woolwich in June 1794. After this type of gun was adop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natal Observatory
The Natal Observatory was an astronomical observatory in the Colony of Natal (now the KwaZulu-Natal province of the Republic of South Africa) from 1882 to 1911. The most important work carried out there was a study of the motion of the moon. Founding of the observatory In 1882 David Gill, director of the Royal Observatory, Cape of Good Hope, requested the government of Natal to establish an astronomical observatory at Durban, in anticipation of the transit of Venus on 4 December that year. Mr Robert T. Pett, third assistant at the Royal Observatory, visited Durban in June that year to expedite matters. A site for the observatory was chosen in the southwest corner of the Natal Botanic Gardens. Gill invited the British astronomer Edmund Neville Nevill (also known as Edmund Neison) to take up the post of government astronomer of Natal and director of the observatory, urging him to arrive in time to observe the transit. Nevill landed in Durban on 27 November and despite proble ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colony Of Natal
The Colony of Natal was a British colony in south-eastern Africa. It was proclaimed a British colony on 4 May 1843 after the British government had annexed the Boer Republic of Natalia, and on 31 May 1910 combined with three other colonies to form the Union of South Africa, as one of its provinces. It is now the KwaZulu-Natal province of South Africa. It was originally only about half the size of the present province, with the north-eastern boundaries being formed by the Tugela and Buffalo rivers beyond which lay the independent Kingdom of Zululand (''kwaZulu'' in the Zulu language). Fierce conflict with the Zulu population led to the evacuation of Durban, and eventually, the Boers accepted British annexation in 1844 under military pressure. A British governor was appointed to the region and many settlers emigrated from Europe and the Cape Colony. The British established a sugar cane industry in the 1860s. Farm owners had a difficult time attracting Zulu labourers to wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Colony
The Cape Colony (), also known as the Cape of Good Hope, was a British Empire, British colony in present-day South Africa named after the Cape of Good Hope. It existed from 1795 to 1802, and again from 1806 to 1910, when it united with three other colonies to form the Union of South Africa, then became the Cape Province, which existed even after 1961, when South Africa had become a republic, albeit, temporarily outside the Commonwealth of Nations (1961–94). The British colony was preceded by an earlier corporate colony that became an Dutch Cape Colony, original Dutch colony of the same name, which was established in 1652 by the Dutch East India Company, Dutch East India Company (VOC). The Cape was under VOC rule from 1652 to 1795 and under rule of the Napoleonic Batavian Republic, Batavia Republic from 1803 to 1806. The VOC lost the colony to Kingdom of Great Britain, Great Britain following the 1795 Invasion of the Cape Colony, Battle of Muizenberg, but it was ceded to the ...

South African Republic
The South African Republic (, abbreviated ZAR; ), also known as the Transvaal Republic, was an independent Boer republics, Boer republic in Southern Africa which existed from 1852 to 1902, when it was annexed into the British Empire as a result of the Second Boer War. The ZAR was established as a result of the 1852 Sand River Convention, in which the Government of the United Kingdom, British government agreed to formally recognise independence of the Boers living north of the Vaal River. Relations between the ZAR and Britain started to deteriorate after the British Cape Colony expanded into the Southern African interior, eventually leading to the outbreak of the First Boer War between the two nations. The Boer victory confirmed the ZAR's independence; however, Anglo-ZAR tensions soon flared up again over various diplomatic issues. In 1899, war again broke out between Britain and the ZAR, which was swiftly occupied by British forces. Many Boer combatants in the ZAR Bittereinder, ...

Orange Free State
The Orange Free State ( ; ) was an independent Boer-ruled sovereign republic under British suzerainty in Southern Africa during the second half of the 19th century, which ceased to exist after it was defeated and surrendered to the British Empire at the end of the Second Boer War in 1902. It is one of the three historical precursors to the present-day Free State (province), Free State province. Extending between the Orange River, Orange and Vaal River, Vaal rivers, its borders were determined by the United Kingdom of Great Britain and Ireland in 1848 when the region was proclaimed as the Orange River Sovereignty, with a British Resident based in Bloemfontein. Bloemfontein and the southern parts of the Sovereignty had previously been settled by Griqua people, Griqua and by ''Trekboere'' from the Cape Colony. The ''Voortrekkers, Voortrekker'' Natalia Republic, Republic of Natalia, founded in 1837, administered the northern part of the territory through a ''landdrost'' based at ...

Local Mean Time
Local mean time (LMT) is a form of solar time that corrects the variations of local apparent time, forming a uniform time scale at a specific longitude. This measurement of time was used for everyday use during the 19th century before time zones were introduced beginning in the late 19th century; it still has some uses in astronomy and navigation. The difference between local mean time and local apparent time is the equation of time. Past use Local mean time was used from the early 19th century, when local solar time or sundial time was last used until standard time was adopted on various dates in the several countries. Each town or city kept its own meridian, so locations one degree of longitude apart had times four minutes apart. This became a problem in the mid 19th century when railways needed clocks for railway time that were synchronized between stations, while local people needed to match their clock (or the church clock) to the time tables. Standard time means that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Time Protocol
The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-Network latency, latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use. NTP was designed by David L. Mills of the University of Delaware. NTP is intended to synchronize participating computers to within a few milliseconds of Coordinated Universal Time (UTC). It uses the intersection algorithm, a modified version of Marzullo's algorithm, to select accurate time servers and is designed to mitigate the effects of variable network latency. NTP can usually maintain time to within tens of milliseconds over the public Internet, and can achieve better than one millisecond accuracy in local area networks under ideal conditions. Asymmetric Routing, routes and network congestion can cause errors of 100 ms or more. The protocol is usually described in terms of a client–server model, bu ...
