System time should be set from RTC time already, by calling rtc7800 from
the linuxrc file in the initrd (partition 2, should be mountable from
the full Debian boot). However if your software load is older and the
system time is not being set correctly, you may need to edit the linuxrc
file to specify the full path to rtc7800.
The most foolproof way to do this after logging in (full debian boot) is
probably this:
# touch /tsfastboot
# touch /fastboot
# reboot
After the reboot you should be at the fastboot prompt. Next is to find
the location of the rtc7800 utility. For example, if you run
/usr/lbin/rtc7800 from the fastboot prompt and that works, then you will
want to use "/usr/lbin/rtc7800" instead of "rtc7800" in your linuxrc
file. (This is just an example, as I don't remember off the top of my
head where rtc7800 lives - but you will want the path to be relative to
fastboot, not the debian root fs...)
Be sure and run the "save" command after updating your linuxrc file, to
commit the ramdisk back to flash. When you exit the fastboot and get
back to Debian you can rm the /tsfastboot file if you want the full
Debian boot again.
