Timing system is a working system to determine and broadcast precise time. Every time at the hour when the radio is listening to the radio will broadcast "beep, beep... ... "The noise. People use it to calibrate their clocks. Where does the right time come from on the radio? It is controlled by the observatory's sophisticated clocks. So how does the observatory know these exact times? We know that the earth turns about once a day, so the stars in the sky rise and fall once a day. Think of the earth as a big clock. The stars in the sky are like the Numbers on the face of a clock. The position of the stars has been well measured by astronomers, which means the number of hours on this natural clock face is known with great precision. An astronomer's telescope is like the hands on the face of a clock. In our everyday clocks, the hands are turned to the face of the clock. In this case, the hands are "fixed" and the "face" is turned. When the stars are pointed at the telescope, the astronomer knows the right time and USES it to correct the observatory clock. In this way, astronomers can always know the correct time from the clock face of the observatory. Then at a certain time of the day, at the hour, for example, we broadcast it over the radio so that we could calibrate our own clocks and watches or do other work as needed.
