Can't you use NTP to set the time on boot i take it they are all connected to the net or a network with one machine connected to the internet setup a ntp server use that to check against at boo time ..
Ahh. I forgot to mention one important fact. These computers are in vehicles on the road. If they cannot figure it out on their own, it wont be figured out.
They do have GPS. However, I have not found an efficient way to share the GPS NMEA recored with nntp and our measurement software, which needs the records with little (read no) delay.
I don't know anything about this, but it's an interesting topic to me (I go sailing :) A quick http://www.google.com/linux?q=gps+nmea+time+ntp showed lots of hits including one that says "The Star Sync GPS receiver plugs into a serial port and interfaces with the generic GPS NMEA driver included with the standard NTP distribution." If there's a generic GPS driver in the NTP distribution, as it claims, couldn't you use that to sync the machines? Or is the key word in your problem 'share'? Aren't the NMEA time sentences broadcast so you just need some 'plumbing' to send it to both destinations (an extra cable, a small shell script, a one-line C program, whatever is appropriate) The gpsd man page has a section on 'use with ntp', for example.
