Specialized intersection for DatetimeIndex objects. May be much faster
than Index.intersection

Parameters
----------
other : DatetimeIndex or array-like
sort : False or None, default False
    Sort the resulting index if possible.

    .. versionadded:: 0.24.0

    .. versionchanged:: 0.24.1

       Changed the default to ``False`` to match the behaviour
       from before 0.24.0.

Returns
-------
y : Index or DatetimeIndex
