Clock Guard is a Windows 95/98/2000/ME/XP/NT/Vista software application that prevents tampering with the pc clock. It can be used for various purposes. A few examples are: 1) Preventing files from being given falsified time/date stamps by manually resetting the system clock and then saving the file. 2) Prevent employees who are using a computer-based time clock from altering the time to allow themselves to punch in at a falsified time. 3) Prevent users who have time limited programs (programs that can only be used at certain times) from accessing these programs at improper times. 4) Prevent people who are paying for pc use on a time basis from resetting the clock to reduce the amount of time they pay for. 5) Prevent people who are restricted to a certain amount of pc time per day (usually children) from resetting the pc clock to give themselves more time.
