I'm working on a oceanographic vessel
ntpgmtaceb is our reference clock that is synchronised with a gps at
the beginning of a cruise.
The drift of this clock is <1ms each day.
It's connected on the lan board of our vessel.

I have removed these two lines
server 127.127.1.0
fudge   127.127.1.0 stratum 10

Then:
service ntpd stop
ntpdate ntpgmtaceb
12 Apr 21:46:22 ntpdate[9860]: adjust time server 192.168.21.5 offset
-0.000252
sec

service ntp start

ntpq -p
     remote           refid      st t when poll reach   delay
offset  jitter
==============================================================================
*ntpgmtaceb      .1PPS.           1 u   20   64  377    0.144
-0.373   0.863

So it's seems to be really better, isn't it?
