hwclock --adjust in slink

["E.L. Meijer \(Eric\)" <tgakem@sg10.chem.tue.nl>]

Hi all,

Since the BIOS clock in my PC at home is lagging behind more than 10
minutes per week, I looked into the correction mechanism of hwclock.  I
am able to set the BIOS clock with hwclock --set --date, and get the
expected result if I try hwclock --show.  The hwclock is called in a
script from runlevels S, 1, and 6:

$ ls /etc/rc?.d/*hw*
/etc/rc0.d/S25hwclock.sh  /etc/rc6.d/S25hwclock.sh  /etc/rcS.d/S50hwclock.sh

All these links call the script with the `start' argument, and as far
as I can tell, this should adjust the clock and the system time using
/etc/adjtime.  Note that if hwclock.sh were called with
stop|restart|reload, the BIOS clock would be set to the system time, but
no K..hwclock script exists.  If I reboot after a hwclock --set ...,
somehow the BIOS clock gets reset to the system time, so that when the
system comes up again, the BIOS clock trails as much as it did before I
--set it to the right time.  This is a on a slink system.  Has anyone
got an idea where the BIOS clock may be reset to its previous value?

TIA,
Eric
