Get date from server

I have my app running in several Win95/98/NT PC's and conected to a Novell Netware 5.0 server. When workstations starts and connect to the server they get the date and time from the server, but the user can change them locally.

Is thare anyway to get the original date and time directly from the server? And the same with Unix AIX server and NT server?

Any idea will be deeply appreciated.

Thanks!
