Hi Richard,
That's great to see this discussion. I'm working on the TAB implementation too.
What I didn’t see in the discussion is how to synchronize gPTP time with
free-running clock.
As I understand, 802.1AS uses free-running clock and corresponding
timestamping, but maintains synchronized

Why? That sounds wrong.
Thanks,

Right. If you want to use

Sounds like a great step backwards. Really.
I didn't quite
Very nice read. But some points:
The rethinking of old-decisions w.r.t. new info may not be valid as the
time to apply them is long gone since the conditions under which those
decisions were made. Maybe the local clock was actually leading or lagging
behind at that time, which might not be the

Richard,
Miroslav,
Thanks for the response.
Yes definitely, tsproc instead of port.c, not sure what I was thinking. I'm
glad I asked.
I'm trying to figure out how to fit an experiment into LinuxPtp and end up with
as much as possible worth pushing back up.
It looks like the dual filters are
