You can set up an NTP server with a hardware reference clock (a GPS
timing receiver) for a minimal cash outlay. Like so:
1. A Sun Ultra 10 (used, <$100 on e-Bay) I'd recommend a minimum of
256MB of RAM. I have a 440MHz processor but it's not required; any
supported processor should do the job.
2. An ATA/EIDE disk drive =>10GB. You may well have something suitable
lying around. $80 will buy you a new 80GB drive.
3. A Motorola Oncore M12+T or M12MT GPS reciever with "evaluation board"
for around $200 from Synergy Systems.
4. Solaris 10 Media kit ($40 from Sun).
5. NTP 4.2.0 or 4.2.1. Free.
Using a discarded PC (with FreeBSD) + maximum $100 for a Garmin GPS18LVC
+ a 9-pin serial connector and a USB cable (used to get +5V power) works
equally well for this purpose, and it is even cheaper! :-)
Use whatever you feel comfortable with!
