This also causes an issue when using stftime and strptime together on Linux
(Ubuntu 20.04.1 LTS).
When encoding a datetime using strftime and decoding with strptime using the
same pattern an error is raised if year < 1000.
Example:
>>> pattern = "%Y-%m-%d"
>>> datetime.strptime(
... datetime(1, 1, 1).strftime(pattern),
... pattern
... )
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.8/_strptime.py", line 568, in _strptime_datetime
tt, fraction, gmtoff_fraction = _strptime(data_string, format)
File "/usr/lib/python3.8/_strptime.py", line 349, in _strptime
raise ValueError("time data %r does not match format %r" %
ValueError: time data '1-01-01' does not match format '%Y-%m-%d'
