Several ideas.

One is the use the PTP style time-stamping available on many modern Ethernet 
interfaces.  Does anybody know how that works?  API?  I assume there is a 
counter in the Ethernet hardware.  How does that counter get converted into a 
time stamp?

Their other approach is to collect much more data.  There are a couple of good 
slides showing the offset with an empty band in the middle.

These are my opinions.  I hate spam.
