I managed to assemble a test fixture similar to the embedded system
I am evaluating deploying linuxptp on, as shown on the diagram below.
System clocks of the three main components are working in synchrony
(apparently) and a change on the system clock of the GM is propagated
after a few seconds
Hi,
Yes, I think so.
The GM will send those values in the Announce message and you pick it up with -w
If it's not, you can configure the offset locally on the client end with -O

Dennis

I think you need to set currentUtcOffsetValid and timeTraceable on the
Hello, Dennys, thank you for chiming in.
From my understanding of the documentation, I assumed
the offset would be taken from ptp4l with the '-w' command
argument. Obviously I am missing some config or doing
something wrong I am not figuring out.
I tried some variations but either they
Hi,
I'm not exactly sure what this tool is doing, but most likely explanation for
the difference between those clocks is due to leap second offset (currently 37
seconds).
I believe RT should be UTC, and the PHC should be TAI (37 seconds in front of
TAI). phc2sys should add the offset (either
