The reference pages indicate that a PPS interface is required.
Most times when somebody says that PPS is required, they leave off the for
decent timekeeping.
I don't have a UT+, but I'd be very surprised if NTP didn't work without PPS.

Currently (based on the comments) the driver won't start and in a previous
incarnation it actually stopped NTPD.
I tried to run a UT+ based ref clock with no PPS. I wanted to use the PPS
but it was not working because I was using a long cable with no drivers. I
gave up and moved the NTP server physically close to the GPS receiver and
it worked. With no reliable PPS the reference clock got rejected.

I've done as much as I can do with my little Adafruit, so I guess it's time to
move to a timing receiver. I already have a UT+, so I might as well make use
of it. My thought was to use the NTP refclock driver and probably take the
sawtooth from SHMEM with a simple C program to pass to my
Hi
If you have a serial “thing” hooked to the GPS, pulling the sawtooth data out
of it is not very hard. They all have some sort of repeating message that
contains time / date / sawtooth information.

If you are running NTP, always you are going to need the PPS. This applies
for any GPS receiver. The data you get over the serial port is never
intended for timingIf you do not use PPS your NTP server will see the
GPS as being such a poor clock that it will likely ignore it in favor of
