In distributed systems, there is no global clock exists rather it uses logical clocks to synchronize the events in the system. When designing or analyzing distributed systems, the logical nature of time is much significant.This concept put forward by Lamport to deal with the logical time. It is fully depend upon causality relation among events. This paper also look into the vector time which is also proposed to capture causality of between events of distributed system. In order to explain things in detail this paper also look into the implementation details of the Lamport’s algorithm.

distributed systems,message passing, causality, logical time, happened before, vector time.
