[ntp:questions] NMEA ref.clock better than my ISP's timeserver?

After first trying the Haicom HI-204III claiming to have PPS in the
manual without really having it, I bought a Garmin 18x LVC and
connected it to the onboard COM-port (COM1) on my Asus M3N78 PRO
mainboard. The Haicom is residing on a USB serial adapter (COM6) to
check how stable the offset is.

Running ntp4.2.5p175-win-x86-bin configured with a couple of
timesources it seems like my ISP's NTP-server gets "disqualified".
Before setting up my own ref.clock I used to have ntp.online.no as my
"favorite NTP-server" thinking it would be the best / most local
server, but now I might offer them to use me as a clock-source? ;)

Anyone wishing to see on their own, might check with ntpq
solbakken.dyndns.org   What kind of accuracy is expectable with a NMEA
GPS with PPS connected to the DCD-line of the serial port? It's not
that I have any special need for extreme accuracy, but I suppose it's
allright having the most accurate clock in the neighborhood. :)



Cheers,
