See the developer and community mailinglist for that question. It has been asked on both mailinglists and should be easy to find with google.

We run atd, you can ask atd to write the system time. More details in the atd sourcecode and the mailinglist posts. Or I can look that up tomorrow (need to leave the train now).

The answer can be found at ​http://wiki.openmoko.org/wiki/Setting_Date_and_Time#Syncing_the_hardware_clock

echo "W\n" > /var/spool/at/trigger

(This bug is the only thing that comes up when feeding the error message from 2008.12 to Google, and references to it feature prominently in other searches, so I thought it's useful to document things here as well)
