Thanks, tried that, but all I get is "No association ID's returned".
I've put the following in ntp.conf:
server 127.127.46.0
fudge 127.127.46.0 time1 0.0 time2 0.0 refid GPS
If I start gpsmon I can see the JSON output at the top, and if I curl
localhost:2947 I get it too. As in my previous post, gpsmon reports
valid fix etc. Not sure what to try next, might have to build my own
function to scrape the time/date and set it with "date -s", though this
does seem a little ridiculous.
