The way I used to format dates using time.strftime does indeed no longer
work.
Python 2.3:
>>> import time
>>> time.strftime("%Y-%m-%d", (2005, 6, 4) + (0,)*6)
'2005-06-04'
Python 2.4 or 2.5:
>>> import time
>>> time.strftime("%Y-%m-%d", (2005, 6, 4) + (0,)*6)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ValueError: day of year out of range
>>> time.strftime("%Y-%m-%d", (2005, 6, 4) + (1,)*6)
'2005-06-04'
I don't actually run into this problem as I've pretty much converted to use
datetime in new code. I also realize that's not documented as the way it
should be done, but I'm fairly certain it was common usage before the
datetime module came along. Still, it is a bit annoying that the
(undocumented, but I think de facto) commonly used idiom no longer works.
(In fact, it always bothered me a bit that I had to even provide the unused
values.)
