QUESTION

Is it safe to adjust the system time on my Perforce server host machine?

ANSWER

It is safe to change the system time on the machine that hosts your Perforce Server. Changing the system time might result in changelists that appear to be submitted out of chronological order. Otherwise, changing the system time does not adversely affect the operation of your Perforce Server. The Perforce Server does not require that changelists be in chronological order; however, users generally expect that changelists are.

Before making any large adjustment to the system time of your Perforce Server host machine, consider stopping your Perforce Server, or stopping Perforce user activity, in order to minimize timestamp inconsistencies in your document change history.
