Also try "man adjtimex" - since the BIOS clock is only used when the PC
is off and Linux controls time when the PC is running, adjtimex will
synchronise with an NTP server as a one-off and then adjust the speed of
the kernel clock to keep it running much more precisely. I've got the
clocks on my PCs accurate enough now that after running for one month
24/7 they're all only out by about one second or so...

Well just in case someone's ever Googling on this thread, I had a very
similar problem to this only without the UPS. It turned out that the
motherboard connector in the ATX power supply was a little loose, and
this would cause the PC to shut down and/or restart for no reason. A
screwdriver to bend the pins a little so they're a bit tighter was all
that was needed to fix that annoying issue!

Cheers,
Adam.

/var/log/faillog is read by the (superuser) "faillog" command and
only stores info about FAILed LOGin attempts (from text mode, kdm/xdm
etc do not store this info).
