Thanks for that.  Yes, the pages generated by MRTG have just the no-cache 
meta-data, so I've added it to my NTP and Network summary pages as well.

I still don't know what happened on Friday!

On Odin I can see the effect of changing to the newer NTP version, there 
seems to be more short-term jitter and perhaps less long-term drift.  We 
will see overnight.  I upgraded Stamsund's NTP as well.
