When I need to determine when people logged in, worst case is last
time the machine was rebooted.  But then, I only do this once per day,
and I keep track of the month of the oldest active login (ok, so it's
just as easy to keep track of the day of the oldest active login...).

No perl, little wisdom, just thoughts...
