As mentioned in the post the times reported are the time stamp in the
receiver packet minus the system clock time when it was received...
negative value indicate the message arrives after the PPS. The polarity of
the reported value is consistent with how Lady Heather makes use of the
value...

Thanks, Mark. I'd missed that in the post. I still find it confusing to
plot positive times as negative ones.
From your data and my own measurements, I feel that using the serial NMEA
stream would, today, be a last resort, as an Internet sync would be
considerably better. Would you agree with that?
Cheers,
David
