Hi David, Thanks for the pointer - but the driver I am using is type 20 (NMEA), so that flag1 is documented as enabling/disabling of PPS signal processing instead.
After some time, the output of "ntpq -c pe -c as -c rl" seemed to stabilize as [1]. The GPS reference seems to be used correctly (as show by the leading "o" in ntpq -c pe" output. However I still don't understand the "reftime/clock" difference, and it seems the two dates are drifting from each other rather than converging, which is unexpected (to me, as a newbie). The frequency field keeps changing, so should I understand that the frequency field is adjusted automatically until the times are in sync?
