I am getting this warning message. I have a feeling that my daughter has discovered that by changing the system time she can get around the Time Restricitons. You need Admin privilages to change the clock, but I discovered that anyone can change the time zone, which may be what she is doing.
Do the Curfew time restrictions work off of the PC Clock of off your server clock?
Curfew time restrictions work, based on child's PC clock. Our server clock has no role in the implementation of time restrictions on child's PC.
Unlike Windows XP, on Windows Vista even a standard user can change the Time Zone. This is the privilege given by the Operating System. I fear, presently, we can't do anything more than reporting the activity (PC System Time was changed).
