Time Synch Multiple Computers

In my department, several computers’ dates and time change. They go into the future. This is due to the way the network is set up with NT and 2000 systems. The system administrator says he can not do anything until everyone, one days, moves to 2k. Until then, it is up to me to help my department. I never have a problem with my system clock.

Now not everyone in my department has Internet access. I do. So I am looking for a time synch program, a freebie, to download so that we can set up several computers to synch their dates and times with mine.

Is that possible? Does anyone know of such a program I can down from the net?

Thanks.
