I don't know how the system clock gets so far off from UTC -- maybe

ok.... so it's a "design feature" ... no big deal... I'll probably
stick with the "-g" option then.....
It's running on a 400Mhz Tibook ... so it is low-powered....

OK. Now we know what's causing it. When your laptop goes into low-
power mode, the clock runs at an incorrect rate. When it comes back
to full-power mode, the clock isn't getting synced.
Maybe there's a way to get control at entering and exiting sleep
mode. I don't know -- never felt the need for a Linux based laptop.
If so (anybody out there know?) you could put in an ntpdate call then.
Or maybe if you read the ntpd man page carefully -- there may be a
back-door way to get the ntpd "sanity window" set *very* wide. It's
worth a try.
