One real gotcha with Julian day numbers is if you try to use them for a
time axis on a plot.
It works fine for long time axes, but if you try looking at high-resolution
data things look really messy.
The problem is that PLOT converts to single-precision before converting
coordinates to data and this means that all values are truncated to the
nearest quarter day (for IEEE floats).
