Yeah, I talked to Truetime - they don't want to sell me a card and let me do a UNIX solution; they want me to purchase a rack mount time server.

I've already got an antenna attached to the GPS receiver as mentioned above. The GPS receiver has several clock outputs that should drive some card in a server just fine ... I just haven't found that card yet :) Thanks for your reply. -- Nathan Norman "Eschew Obfuscation" Network Engineer GPG Key ID 1024D/51F98BB7 http://home.midco.net/~nnorman/ Key fingerprint = C5F4 A147 416C E0BF AB73 8BEF F0C8 255C 51F9 8BB7
