- The range really is ``0`` to ``61``; according to the Posix standard this
- accounts for leap seconds and the (very rare) double leap seconds.
- The :mod:`time` module may produce and does accept leap seconds since
- it is based on the Posix standard, but the :mod:`datetime` module
- does not accept leap seconds in :meth:`strptime` input nor will it
- produce them in :func:`strftime` output.
+ Unlike the :mod:`time` module, the :mod:`datetime` module does not support
+ leap seconds.
