-------------------------------------+--------------------------------------
 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.
