[ntp:questions] Come back PPS I miss you!

So.. I am replying to my own posts too..
Started ntpd in debug and seeing a lot of GPS_NMEA(1) PPS_RELATE_NONE
>From the source:
* The function returns PPS_RELATE_NONE (0) if no PPS edge correlation
* can be fixed; PPS_RELATE_EDGE (1) when a PPS edge could be fixed, but
* the distance to the reference time stamp is too big (exceeds +/-400ms)
* and the ATOM driver PLL cannot be used to fix the phase; and
* PPS_RELATE_PHASE (2) when the ATOM driver PLL code can be used.
So does this mean basically I am screwed and can get on with life?
Many thanks,
Mark

Hi All, and probably Dave specifically,
I have tried everything with my PPS, inverting it in hardware, in software (flag2 1) I just can't get PPS tally to come on.
Today, I restarted and noticed:
refclock_params: time_pps_setparams: Unknown error: 45
in event log.
Here is the usual:

I have just restarted so it takes many moons to settle down again, if any idea what's going on, now would be a good time, before it settles down too much?
Many thanks, Mark
