Sun dials show the time passing by using the relatively constant motion of the Sun and the changing angle of the sun’s shadow cast by the sun dial. For millennia, humans have been measuring time in various ways, some include tracking the movements of the sun with sundials, the use of water clocks, candle clocks, and hourglasses. An automaton clock is a timekeeping device that uses animated figures to mark the passing of the hours. The oldest clock was most likely Earth as it related to the Sun, Moon, and stars. The coarsest sundial measurements were good to within an hour, but sundials were the only commonly used clocks until as late as the mid-17th century and the more modern ones had accuracies as good as 15 to 30 seconds. This first known measurement of time was the precursor to the modern day analog clock. Time and clocks: a description of ancient and modern methods of measuring time by Cunynghame, Henry H.

Events in time are always accompanied by the mental image of places suggesting that time … But keeping track of time is something that mankind has struggled with for many thousands of years. To increase the accuracy of water clocks, some were mechanized to make the flow of water as constant as possible by regulating the water pressure. As mentioned before the easiest way to track time is to record the movement of the sun across the sky. Other time-keeping methods that relied on the steady change in some natural medium included incense clocks, sand clocks (otherwise known as hourglasses), and oil lamp clocks. In Plato’s clock, water was siphoned off into an additional vessel once it reached a certain level, and the additional vessel contained a tube with a narrow slit. How Do We Measure Time? This is most easily done by measuring the shadow cast by a vertical stick. Many Westerners felt that globalization required more accurate and predictable ways of measuring time.
