[fpc-pascal] Getting Last User Input reliably

[Travis Siegel]

If there's some sort of a configuration file, just write out the 
time/date info at the time of leaving the input, then when that routine 
gets called again, grab the current time/date, and perform a 
comparison.  That should allow you to bypass any roll overs of any kind 
(unless it goes past the operating system's time keeping abilities), 
which isn't likely.
