* The :mod:`datetime` module has a new type :class:`~datetime.timezone` that
implements the :class:`~datetime.tzinfo` interface by returning a fixed UTC

:class:`float` and divided by :class:`float` and :class:`int` objects.
And :class:`~datetime.timedelta` objects can now divide one another.
(Contributed by Alexander Belopolsky in :issue:`1289118`, :issue:`5094`,
:issue:`6641`, and :issue:`2706`.)
* The :class:`~datetime.datetime` class and the :meth:`datetime.date.strftime`
method are no longer restricted to years after 1900. The new supported year
range is from 1000 to 9999 inclusive.

* The ``strftime()`` method of :class:`~datetime.date` and
:class:`~datetime.datetime` are no longer restricted to years >=
1900. The new supported year range is [1000, 9999]. (Contributed
by Alexander Belopolsky and Victor Stinner in :issue:`1777412`)
.. XXX Add a section on time module.
* The :func:`time.asctime` and :func:`time.ctime` functions no
longer call C library asctime. (Contributed by Alexander
Belopolsky in :issue:`8013`.)
* Changed the rules for using 2-digit years in time tuples. The
:func:`time.asctime` and
:func:`time.strftime` functions will now format any year when
``time.accept2dyear`` is false and will accept years >= 1000
otherwise. :func:`time.mktime` and :func:`time.strftime` now
accepts full range supported by the OS. Conversion of 2-digit
years to 4-digit is deprecated. (Contributed by Alexander
Belopolsky and Victor Stinner in :issue:`10827`.)
* The rules for two-digit years in time tuples have changed. Now, the
:func:`time.asctime` and :func:`time.strftime` functions will format any year
when :attr:`time.accept2dyear` is false and will accept four-digit years
otherwise. The :func:`time.mktime` and :func:`time.strftime` functions now
accept full range supported by the operating system. Conversion of two-digit
years to four-digit is deprecated.
