This is for after 3.11, because I'm staying away from feature

I'm looking at an NMEA mode gpsmon now.  I see a UTC time in the Cooked PVT
box, a PPS offset in the GSA + PPS box, and two time entries in the RMC
and GGA boxes. What do you mean by "offset time" that none of these covers?

Now I'm looking at SiRF mode.  There's a UTC time entry in the top box and
a GPS time entry in the window for Packet 7.  What else do you want, exactly?
I am not getting anything definite from "serial (non-PPS) offset".
