It uses the projection direction of the sun to determine and divide the time.
Human beings have used sundials for a long time. The ancient Babylonians began to use sundials 6000 years ago, and China was in the Zhou Dynasty 3000 years ago. A sundial can show not only the time of the day, but also the solar terms and months. Of course, its disadvantages are also obvious. It can't be used when it is heavy and can't see the sun, such as cloudy days and nights.
