Here is an updated patch with _M_ prefixes on members instead of __
and no uglification of parameters and automatic vars in *.cc. No changes
otherwise, bootstrapped/regtested on x86_64-linux and i686-linux
successfully.

PR libstdc++/77760
* include/bits/locale_facets_nonio.h (__time_get_state): New struct.
(time_get::_M_extract_via_format): Declare new method with
__time_get_state& as an extra argument.
* include/bits/locale_facets_nonio.tcc (_M_extract_via_format): Add
__state argument, set various fields in it while parsing. Handle %j,
%U, %w and %W, fix up handling of %y, %Y and %C, don't adjust tm_hour
for %p immediately. Add a wrapper around the method without the
__state argument for backwards compatibility.
(_M_extract_num): Remove all __len == 4 special cases.
(time_get::do_get_time, time_get::do_get_date, time_get::do_get): Zero
initialize __state, pass it to _M_extract_via_format and finalize it
at the end.
(do_get_year): For 1-2 digit parsed years, map 0-68 to 2000-2068,
69-99 to 1969-1999. For 3-4 digit parsed years use that as year.
(get): If do_get isn't overloaded from the locale_facets_nonio.tcc
version, don't call do_get but call _M_extract_via_format instead to
pass around state.
* config/abi/pre/gnu.ver (GLIBCXX_3.4.30): Export _M_extract_via_format
with extra __time_get_state and __time_get_state::_M_finalize_state.
* src/c++98/locale_facets.cc (is_leap, day_of_the_week,
day_of_the_year): New functions in anon namespace.
(mon_yday): New var in anon namespace.
(__time_get_state::_M_finalize_state): Define.
* testsuite/22_locale/time_get/get/char/4.cc: New test.
* testsuite/22_locale/time_get/get/wchar_t/4.cc: New test.
* testsuite/22_locale/time_get/get_year/char/1.cc (test01): Parse 197
as year 197AD instead of error.
* testsuite/22_locale/time_get/get_year/char/5.cc (test01): Parse 1 as
year 2001 instead of error.
* testsuite/22_locale/time_get/get_year/char/6.cc: New test.
