In many distributed applications, identifying the sequence of event occurrence is useful. Doing so requires lo cal clocks to be properly synchronized with each other. This paper presents a method of pseudo-synchronization of clocks by making use of the occurrence time of events included in direct “happened-before” relations. The basic idea is to approximate the actual clock shift between two clocks using the minimum transmission delay of messages between a pair of hosts. Evaluation results suggest that non-base clocks are closely synchronized with a base clock without violating the direct “happened-before” relations.
