Hello,
    I'm having an issue with getting time from gpsd.

My setup is:
Raspberry Pi 3 running Jessie Lite
USB U-Blox gps

gpsd is receiving NMEA from the GPS, cgps also shows time and position
properly.

My chrony.conf is:

server 0.us.pool.ntp.org
server 1.us.pool.ntp.org
server 2.us.pool.ntp.org
server 3.us.pool.ntp.org
driftfile /var/lib/chrony/drift
allow
refclock SHM 0 refid GPS precision 1e-1 offset 0.9999 delay 0.2
makestep 1 -1

Chronyc sources shows this:

$ chronyc sources
210 Number of sources = 5

This system is going to be used on a boat and might not have internet.  I
can tell that both programs are accessing the shared memory using ipcs -m:

------ Shared Memory Segments --------
key        shmid      owner      perms      bytes      nattch     status

0x4e545030 0          root       600        80         2

0x4e545031 32769      root       600        80         1

Any idea why chrony isn't getting time from the GPS?

Thanks
