         This method takes a time zone (tz) naive Datetime Array/Index object
         and makes this time zone aware. It does not move the time to another
         time zone.
-        Time zone localization helps to switch from time zone aware to time
-        zone unaware objects.

+        This method can also be used to do the inverse -- to create a time
+        zone unaware object from an aware object. To that end, pass `tz=None`.
