Also with start-datetime and end-datetime which is even uglier - the
overlap of datetime of occurrence vs datetime of display is really ugly,
especially when you're trying to visually display "point of ignition",
"bloom", "fading away" if you get my meaning.  A sort of heat map but
automated.

Anyway, as may be obvious from the above I'm also very interested.  Years
ago in the IJGIS there was an article about design of spatial databases
with time measures, but sad to say all my IJGIS issues have long since been
recycled.

Maybe someone is doing this in d3.js?  Seems like a logical framework for
this sort of thing...
