Hi

One of my ntp servers (moni0) uses another ntp server (gps) as time
source. The gps server gets it's time by gps ;-)
As you can see in this graph the offset is quite constant:

But I wonder why it shows such big jitter values? I thought jitter is
only a change in the offset.

As you can see in the next graph the gps servers is really close to
it's pps source, too:

BTW: Why shows the last graph a constant jitter value of 0.015 ms all
the time?
