[ale] file modification time via shell script

[yahoo at jimpop.com (Jim Popovitch)]

I'v got an electronic voting machine that I need some help hacking on..
NOT!  (but I did get your attention...)  ;-)

Here's what I am trying to do however:  I need to run a script (via
cron) that first determines if a log file changed since the last time
the script ran before it does further processing.  Ideas?
