And on what hardware do you think you can obtain 10ns resolution RELIABLY 
at the software level in the Unix environment and under FreeBSD?

Answer: NONE!

The actual usable resolution of a timing source is determined by the 
maximum slop in ANY part of the complete system.

I challenge you to get actual REPEATABLE 10ns results while a multi-tasking
anything is running on the recipient of that data.
