germany + (09622) 30 265
The chip I used is called "U2775" I belive it has order# 18 29 66-23
There is also a complete clock Incl RS-232.

Your stratum will be one, because the ref-clock has zero:
xntpdc> loopinfo

poll adjust: 30
watchdog timer: 52 s

Here is my ntp.conf:
driftfile /etc/ntp.drift

peer 127.127.8.20
statsdir /home/ntpstats/
filegen peerstats file peerstats type day enable

filegen clockstats file clockstats type day enable
Here is the patch to xntpd to configure the DCF gadget:
