Login Script to synchronize clocks

I wrote a logon script to have the users clocks synchronized with the clock of the pdc. @echo off
net time \\tsc1-pdc /set /yes
where tsc1-pdc is my servers name. The only problem is is works for the administrators but not for any of the users. I even added the domain users and everyone groups to the change system time in user manager but that didn’t help either. I thought a logon script overrides any rights a user has. Please tell me how to get this script to work.
