Classé sous :
Calling strftime on a date/datetime instance on py24/py26 will raise a value error like this:
>>> from datetime import date
>>> date(1800,1,1).strftime('%d%m%Y')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: year=1800 is before 1900; the datetime strftime() methods require year >= 1900
Quite annoying heh ?
There is a bug related on the python bugtracker here : http://bugs.python.org/issue1777412
The work here was to integrate the working patch in the bugreport to py24 and py26 python packages which are in minitage.
So now, with minitage's pythons, you can work with very old dates by default !!!
Just issue:
virtualenv --no-site-packages --distribute minitage source minitage/bin/activate minimerge -s minimerge -v python-2.6 (or 2.4)
And you can use the following interpreter which support those old ages:
minitage/python-2.6/parts/part/bin/python
And of course the related patch does not break anything:
