I am writing an application that takes the system time and does some caculations. The app will calculate how much time the employee was at work.
The app will be installed on one PC. The app generaly has two bottons; "In" "Out". Every morning the employee will enter his name and will click the IN bottun. And at the end of his work he will click OUT.
The app will work on win9x nt and xp
The problem is that if the user will be able to change the system's time than the app is worthless.
How do I overcome that?
(Please don't tell me "atomic clock" since the pc is not connected to the Internet. also hiding the clock can be unhide or can be changed with time command)
