Abstract: The problem of clock synchronization in the current simulation system and Network Time Protocol(NTP) are introduced in this paper. A software clock synchronization algorithm with high precision, which is realized by importing the mode of “master and slave servers” and the mechanism of time progress and event login in the client on the basis of the NTP is proposed. This algorithm is suitable for the distributed simulation system. The design of a time synchronization system and an experimentation are presented. According to the analysis of experimental data, the algorithm is validated simple and effective.
