ntpq change in behaviour

Hello,

I noticed that since Friday the output of

/usr/bin/ntpq -c kerninfo|/bin/awk -e '/pll offset:/ {o=$3; if (o < 0) o
= -o; print o*1000000;}' -e '/estimated error/ {print $3*1000000;print
1;print "ntpstat"}'

gives different results than before.

On one box I used to see an mrtg graph with estimated error in the low
100's of µs. Absolute offset would be roughly moving in the mid 100's of µs.

Now I see a zero offset and solid estimated error. (5)


On the other box that runs kernel hardpps I see a similar change where
offset is solid at 6; this used to be a changing number.


Friday is the last time I updated the local ntpsec git tree and built
ntpsec. This tree is at commit 034de514d90ef57df732c792e8bbe0fb48720cb9.



Is this intended behaviour?
Can someone please explain?

Thanks!

Kind regards,
Udo
