I
want to use chrony to synchronize the system clock between two
computers (with no connection between them), each equipped with a gps
(gps emmit a pps). The computers can run during about 5-8 hours and
the gps signal can be lost. The goal is to achieve the best clock's
synchronization between both computers.
I read the tutorial on chrony, linuxpps and gpsd but instead of using linuxpps, I want to use gpsd for monitoring the pps.
I tested with the following configuration:
refclock SHM 0 refid GPS refclock SHM 1 refid PPS lock GPS
but
I did not work (I saw some Pulse rejected from gpsd, but it is another
problem), so does chrony supports the SHM PPS of gpsd ?
