Clock synchronization in distributed systems

Clock inaccuracies cause serious problems and troublesome in distributed systems. The clocks of different processors need to be synchronized to limit errors. This is to have an efficient communication or resource sharing. Hence the clocks need to be monitored and adjusted continuously. Otherwise, the clocks drift apart. Similarly clock skew also introduces mismatch in time value of two clocks. Both these are to be addressed to make an efficient usage of features of distributed systems. In the proposed work clock synchronization is accomplished by adopting a token ring approach. The clocks are both internally and externally synchronized.
