>You started with NTP and my responses have all been in that context.  The Soekris modification is an example of time-nut pursuit of a goal.  A side effect was a very good NTP local clock.  If you goal is a very good local clock then that's an approach.  If you goal is time transfer using NTP over ethernet then it's >over-kill.  I'm not sure of your  goal.

Not at all Paul, my original question was about the APU2, I plan to use it as a router and I thought the GPS would be a fun addition.
The discussion sort of veered towards PTP and I apologize, I should've changed the subject to match.
