Logical clock

Mechanism for capturing chronological and causal relationships

A logical clock is a mechanism for capturing chronological and causal relationships in a distributed system. Often, distributed systems may have no physically synchronous global clock. In many applications, if two processes never interact, the lack of synchronization is unobservable and in these applications it is enough for the processes to agree on the event ordering rather than the wall-clock time. The first logical clock implementation, the Lamport timestamps, was proposed by Leslie Lamport in 1978.
