WebSCALAR TIME Lamport proposed the scalar time representation in 1978, for totally ordering events in a distributed system. In this representation, the time domain is the set of non-neg- ative integers.

Consistency property: Scalar clock always satisfies monotonicity. A monotonic clock only increments its timestamp and never jump.Hence it is consistent. 2.
