Incrementally builds C99+ datetime support with addition of
%C. Also adds tests (for%Cand for%ywith%C) and updates documentation.Continued effort from PR: #140647, #144819, #144896.
Documentation drops (0) footnote and notes that zero-padded century numbers are optional (for centuries 0 to 99).
Passed all tests.
Passed patchcheck.
Issue: #140715
Note, this feature runs against
datetime.MINYEAR=1; C99 strptime reads century 0 as year 0. Initial PR proposes settingyear=1forcentury=0, otherwise the object's year is calculated asyear=100*century.str*timeto C11 format codes #140715📚 Documentation preview 📚: https://cpython-previews--145955.org.readthedocs.build/
