The standard clock system, also known as the master clock, provides a standard time signal for the equipment that needs time service. The slave clock is also called the clock, which receives the standard time signal of the master clock. The master clock can receive GPS, Beidou, GLONASS, and other satellite signals as a standard time signal to provide standard time signals for computer systems, secondary clocks, monitoring equipment, weak electronic systems, and other equipment that needs time service.
With the development of technology, mechanical master clocks are gradually being replaced by quartz master clocks and atomic clocks. And the slave clock has also changed from a single receiving signal mode to multiple different receiving signal modes.
