Good point, we are missing some of those topics. While I think this *is* a good avenue for learning about those topics, I have to question what the true motivations for a date-range recipe should be; Is the recipe an avenue for instructing on one method (interop) or another (3rd party library), or is this a recipe intended solely to answer a specific and largely unanswered problem?

I personally lean towards the most "batteries included" approach of the two, but I think I'd still be amenable to included two alternative approaches to the same problem.
