How to avoid changing the time/system time?

[eneyardi]

I have a form that shows the current time, My problem is when users change the system time and it will update the time in the program. Is there any idea on how to avoid users change the system time? or even they can change the system file, i want the program time will not be affected.

My friend, the time in your program is a regional settings, I dont think if you can manage to have a time of your own.
If you want to disable the form after sometime, try to record the time changes and compare with previous time and date or Count howmany times should the form be opened before disabled
