We are one of the Best Master Slave GPS Clock Manufacturers and Suppliers in New Delhi. The idea of the Master and Slave clock originated in the British Empire and has been used ever since. All slave clocks will be connected to the master clock via a data cable, and the master clock can be linked to GPS. All of the slave clocks will display the same time as the master clock. There won't be any time differences between the slave and master clocks. All of the slave clocks will show the same time throughout the year, regardless of what the master clock shows.
