The current sexagesimalsystem of time measurement dates to approximately 2. BC from the Sumerians. The Egyptians divided the day into two 1. They also developed water clocks, which were probably first used in the Precinct of Amun Re, and later outside Egypt as well they were employed frequently by the Ancient Greeks, who called them clepsydrae. The Zhou dynasty is believed to have used the outflow water clock around the same time, devices which were introduced from Mesopotamia as early as 2. BC. Other ancient timekeeping devices include the candle clock, used in ancient China, ancient Japan, England and Mesopotamia the timestick, widely used in India and Tibet, as well as some parts of Europe and the hourglass, which functioned similarly to a water clock. The sundial, another early clock, relies on shadows to provide a good estimate of the hour on a sunny day. It is not so useful in cloudy weather or at night and requires recalibration as the seasons change if the gnomon was not aligned with the Earths axis. The earliest known clock with a water poweredescapement mechanism, which transferred rotational energy into intermittent motions,1 dates back to 3rd century BC in ancient Greece 2Chinese engineers later invented clocks incorporating mercury powered escapement mechanisms in the 1. Iranian engineers inventing water clocks driven by gears and weights in the 1. The first mechanical clocks, employing the verge escapement mechanism with a foliot or balance wheel timekeeper, were invented in Europe at around the start of the 1. The invention of the mainspring in the early 1. The pendulum clock remained the most accurate timekeeper until the 1. World War 2. Although initially limited to laboratories, the development of microelectronics in the 1. Atomic clocks are far more accurate than any previous timekeeping device, and are used to calibrate other clocks and to calculate the International Atomic Time a standardized civil system, Coordinated Universal Time, is based on atomic time. Timekeeping devices of early civilizationseditMany ancient civilizations observed astronomical bodies, often the Sun and Moon, to determine times, dates, and seasons. FR-EE Astro Boy Full Movie'>FR-EE Astro Boy Full Movie. The first calendars may have been created during the last glacial period, by hunter gatherers who employed tools such as sticks and bones to track the phases of the moon or the seasons. Stone circles, such as Englands Stonehenge, were built in various parts of the world, especially in Prehistoric Europe, and are thought to have been used to time and predict seasonal and annual events such as equinoxes or solstices. As those megalithic civilizations left no recorded history, little is known of their calendars or timekeeping methods. Methods of sexagesimal timekeeping, now common in both Western and Eastern societies, are first attested nearly 4,0. Mesopotamia and Egypt. Mesoamericans similarly modified their usual vigesimal counting system when dealing with calendars to produce a 3. Ancient Egyptedit. Ancient Egyptian sundial c. BC from the Valley of the Kings. Daytime divided into 1. The oldest known sundial is from Egypt it dates back to around 1. BC 1. 9th Dynasty, and was discovered in the Valley of the Kings in 2. Sundials have their origin in shadow clocks, which were the first devices used for measuring the parts of a day. Ancient Egyptian obelisks, constructed about 3. BC, are also among the earliest shadow clocks. Egyptian shadow clocks divided daytime into 1. One type of shadow clock consisted of a long stem with five variable marks and an elevated crossbar which cast a shadow over those marks. It was positioned eastward in the morning, and was turned west at noon. Obelisks functioned in much the same manner the shadow cast on the markers around it allowed the Egyptians to calculate the time. The obelisk also indicated whether it was morning or afternoon, as well as the summer and wintersolstices. A third shadow clock, developed c. BC, was similar in shape to a bent T square. It measured the passage of time by the shadow cast by its crossbar on a non linear rule. The T was oriented eastward in the mornings, and turned around at noon, so that it could cast its shadow in the opposite direction. Although accurate, shadow clocks relied on the sun, and so were useless at night and in cloudy weather. The Egyptians therefore developed a number of alternative timekeeping instruments, including water clocks, and a system for tracking star movements. The oldest description of a water clock is from the tomb inscription of the 1. BC Egyptian court official Amenemhet, identifying him as its inventor. There were several types of water clocks, some more elaborate than others. One type consisted of a bowl with small holes in its bottom, which was floated on water and allowed to fill at a near constant rate markings on the side of the bowl indicated elapsed time, as the surface of the water reached them. The oldest known waterclock was found in the tomb of pharaoh. Amenhotep I 1. 52. BC, suggesting that they were first used in ancient Egypt. Another Egyptian method of determining the time during the night was using plumb lines called merkhets. In use since at least 6. BC, two of these instruments were aligned with Polaris, the north pole star, to create a northsouth meridian. The time was accurately measured by observing certain stars as they crossed the line created with the merkhets. Ancient Greece and RomeeditCtesibiuss clepsydra from the 3rd century BC. Clepsydra, literally water thief, is the Greek word for water clock. Water clocks, or clepsydrae, were commonly used in Ancient Greece following their introduction by Plato, who also invented a water based alarm clock. One account of Platos alarm clock describes it as depending on the nightly overflow of a vessel containing lead balls, which floated in a columnar vat. The vat held a steadily increasing amount of water, supplied by a cistern. By morning, the vessel would have floated high enough to tip over, causing the lead balls to cascade onto a copper platter. The resultant clangor would then awaken Platos students at the Academy.
