Since we didn't spring for the real time clock as part of the SBC we need correct the date each time we reboot. The command is
$root> ntpdate ntp.org
The startup script /etc/init.d/ntpdate already existed. The links in the directory /etc/rcS.d get started during boot with the "start" command. The scripts are executed in order from S00 to S99. I used S51 so ntpdate will run after the hwclock scripts run (and fail).
root$ ln -s /etc/rcS.d/S51ntpdate.sh /etc/init.d/ntpdate
