IMHO “+ 1 days” and “+ 24 hours” are two different things. Date arithmetic is full of messy things like that. “+ 1 month” is another example of that (which the datetime module punts completely and can be a source of endless bikeshidding).
Er, to be exact, it's an accurate statement of imprecision (although when talking about time and computation, both "accuracy" and "precision" are ambiguous). Fortunately, there's a "tim" in "time"!
