I am develoing one application which is fully depend on system time. But as i cannot restrict the system users from editing the system time, it will cause problem to me.

Is there any way from the application to trap the reseting the system time.

You can keep the user from editing things within your program, but unless you have a very intimate knowledge of the OS, you can't stop the user from editing the system time. It is the right given by the BIOS of the user to edit his/her system time. If you tell me why you want to keep the user from editing the system time, I might be able to help you develop an alternate solution...

If you are reading the system time at a specific rate (say every minute or so) and the difference between current time and the previous time is not 1 minute (give or take a tolerance of maybe 5 seconds), the time was reset.

But I don't want to restrict editing system time. One which i need is to track the change. I was planning to use Timer and continuously checking the system time after a fied interval of time. But as the timer message is having low priority I feel that this will not be accurate. Thats why I am searching for an alternate way.
