The widespread clock synchronization standard, IEEE 1588, is purely master-slave based. The inherent disadvantage is that a failure of the master requires the election of a new one, during which the network nodes cannot be synchronized. This paper proposes a compatible extension to the standard introducing architecture for fault-tolerant and seamless distribution of time information. In this paper the protocol is implemented using RTOS in a LAN with processor as one node. The processor having real time clock and is programmed for the synchronization between systems. The processor is the grand master clock which is going to generate clock pulses for all other nodes in the LAN.
