Well, I'd rather avoid playing with system files. Is there a trigger
that I can use to run a script when the laptop wakes? I could run a
script which does no more than record the current timestamp. Then,
when I discover that the machine is running, I can compare the current
unixtime with the timestamp that was written when the machine woke.

I would only run the script upon wake, like the script I just
mentioned in point 2.
Thanks.
