What prevents the by passing of limits by simply changing the clock on the computer?
The first line of defense should be that the kids have a Limited Account in Windows. That will prevent changes to the system date and time, since only Windows users with Administrative rights can change the time and date using the control panel. However, if the Windows account that ComputerTime is running in has Administrative rights, ComputerTime adds additional protections to prevents the changing of the clock on the computer by monitoring the system time. If for any reason you actually do need to reset the system time, for legitimate reasons, here is what you should do: • Log out of ComputerTime, and return to the main ComputerTime logon. • Click on the “Admin Logon” button, and enter the ComputerTime Admin password. Click OK. • Now you are logged on, but aren’t being monitored. Neither is the clock.
