A while back, I decided to work with floating point Julian dates instead of DateTime objects, but now that I think about it, that was mostly for my convenience, and it may be time to revisit that decision.
In any case, I am still curious about the questions I posed. Could you expand a bit about inheriting from types? How would that differ from my type definition?
