5323	Proposal: Associated type difference_type for chrono::time_point	Joachim Faulhaber	viboes	"Similar to other c++ types that have comparable distances, but no fixed zero, like `T*` or `random_access_iterator<T>`, `chrono::time_point` shall have `difference_type` as associated type. The difference type of time_point is its a chrono::duration.
