They are not "out of sync". They just interpret "raw numbers" provided
by hardware in a different way. :-)

At least in Linux 'hwclock' command has various options which affect
how hardware data are interpreted. See 'man hwclock' for gory details.
Due to various hardware clocks (there is more than two even if this
sounds strange) this does not always work. If an offset is constant
you may manipulate your system clock in startup scripts; that means,
if you insist on running billgware which will whack your clock every
time. Something like that, but this is kind of gross:

  if [ "$(date %Y)" -ge $crazy_value ] ; then
      date --set='-20 years'
  fi

Take care about doing that early enough or you will get complaints
about weird time-stamps in various places.
