Hey


Thanks for the reply. I got my program to feed ntpd with the PPS signal.


Now the only thing I am struggeling with is that I need to edit (linechange or something) ntp.conf file and restart ntp after boot.

Do you have any idea as why I need to do that? 


With kind regards,

Henning Håkonsen

If you are on a RasPi or BBB then check out the gpsd-time-service-howto.txt
in the tarball.  The solution is well documented.

There are important improvements to this in git head, so be sure to
try git head and not anything from your distro.
