I agree.  See issue 9079.

We can do that.  I'll experiment with this approach within issue 9527.

No, I don't want  time_strftime in _basictime.  I want
datetime_strftime to be independently implemented and freed of legacy
restrictions on the year range.   The _basictime module should include
a very simple wrapper around system strftime if we want to keep using
it in datetime.py, but it would be best to have complete pure python
implementation of both strftime and strptime.
