+ astonishment about getting `1.hour.inspect # => 3600 seconds`.
+
+ Compatibility: The duration's `value` remains the same, so apps using
+ durations are oblivious to the new time periods. Apps, libraries, and
+ plugins that work with the internal `parts` hash will need to broaden
+ their time period handling to cover hours & weeks.
