Time Sync and Logon Scipts for NT

I am wondering how to write logon scripts for NT users. I want to sync the time on the workstations with the server time. I have a vague idea of how to accomplish this but due to my experience level I can’t get it to work. Any assistance would beappreciated. I am only dealing with 5 users who can all have the same logon script.
thanks,
Brian
