This paper presents an improved method in solving the problem of time lag experienced by digital clocks, which are often due to power loss. The design concept in this paper was validated by designing a prototype. A master clock connected to a real time clock transmits time through a transceiver to slave clocks within a defined region to ensure that time displayed on the clocks is synchronized. This results in the master clock updating the slave clocks every second through the transceivers to maintain non-varying time. The setup in this paper verified the possibility of having synchronized time which is always accurate with the real time clock.
