+(1)
+   When used with the :func:`strptime` function, the ``%p`` directive only affects
+   the output hour field if the ``%I`` directive is used to parse the hour.
+
+(2)
+   The range really is ``0`` to ``61``; this accounts for leap seconds and the
+   (very rare) double leap seconds.
+
+(3)
+   When used with the :func:`strptime` function, ``%U`` and ``%W`` are only used in
+   calculations when the day of the week and the year are specified.
+
+(4)
+   For example, if :meth:`utcoffset` returns ``timedelta(hours=-3, minutes=-30)``,
+   ``%z`` is replaced with the string ``'-0330'``.
