I was seeing 0 secs per hour:-(
I discovered the answer. The main server was running ntpd on a 24/7 basis.
About 11 days ago my isp allocated me a new ip address (after 2 years of it
being the same despite being dhcp allocated). As NTP is a UDP service it
must have sent the source ip address in the message to the time server so it
can see a reply. It was sending the old address and as a result never seeing
the reply. It therefore became a stratus 16 server
My workstation was configured to become a stratus 10 server from the local
clock so that it could continue when the main server was available. It
therefore was not trying to even synchronise between the two.
