in reply to Computer User Timer

I suggest Time::HiRes and the setitimer/getitimer functions. For docs go here.
You could set the timer using setitimer. Then to display a a timer to the user, use getitimer and keep updating a formatted line via some method like 'formline' (which I use personally for displaying progress bars). Eventually, setitimer is going to send a SIG_ALARM, which you can catch in a subroutine that implements whichever method of 'stopping' the user from continuing to use the PC that you decide to use (e.g. I don't know what exactly to do to prevent access to the PC when the timer expires).
