I was just looking at the pool web graphs and noticed that many

I would also prefer log scale for the y axis, for the same reasons.
rrdtool gives me empty graphs for some reason when I use the --
logarithmic option. I haven't looked into it much, but I think maybe
it's because it doesn't work with auto-scaling.
Also I'm not sure I'm comfortable with that much being read into the
graphs. Remember that it's just comparing your time with the local
ntpd. Good enough to determine when your clock runs wild or the
network heavily saturated; not good enough to determine if you are 10
or 30ms off.
As long as we're making a wish list, possibly a counter-suggestion:
The y axis should show not the absolute value of the offset, but show
the offset as both above and below zero.
Adding that kind of extra detail feels wrong given the simplistic
nature of the monitoring system.
