I have written (attempted to write?) reasonably versatile date & time axis
routines in both Direct Graphics and Object Graphics and found it somewhat
easier with Object Graphics. No, on second thoughts, much easier! With
object orientation you can create an object, query its properties, adjust
them etc and then wrap the result in a user-friendly, self-contained object.
Direct Graphics routines for the same purpose tend to be less robust and to
change the graphics system state in a way that can have unforeseen effects
later.

But I'll have a look at timebox...
