Mike. That worked. Still curious why Marco's approach works for him but not on my machine. I am working on a win machine today-maybe something about the way it handles floating point etc.
   I will use your approach-it would be nice if the Octave team would incorporate this into their code at some point so it is less "patched together". I would expect plotting time series is pretty common and something a little more streamlined would be nice. I vaguely recall that Matlab was similarly afflicted.

Thanks again both of you for your help!

without the axis, it works for me.
Use the "graphics_toolkit gnuplot" as fltk has problem on
numbers too near and large (due to resolution on float)
Or subtract away the irrelevant date part of the datenum values

    xdatenum = xdatenum - datenum ([2018, 1, 1, 0, 0, 0]);

I thought we had a FAQ entry about this, but I don't see one.
