RE: OT: NTP hardware
For a solution developed by amateur radio operators have a look at:
www.tapr.org in the area titled TAC32.
May be some help however please note that some construction is required.
Software is available for to maintain system clock of a linux system very
accurately however I cannot recall what is was called. I am sure it would be
outlined at the above website.
Cheers
David

With a short search of GOOGLE on "GPS Time Card", I got
http://www.truetime.com which apparently makes PCI, ISA and other GPS
boards to use for clocking. Debian has software in woody/potato that'll
talk to some of these boards. With Selective Availabilty now removed,
they should be amazingly precise.
I'm sure they're other places to get these boards. Just need an antenna
and some software so talk to it, I guess.
