The documentation for strftime and strptime behavior strikes me as a bit jumbled right now. The behavior of datetime.datetime.strptime is explained by a reference to time.strptime, which in turn references time.strftime to explain the format string.

The docs for the datetime.{datetime,date,time}.strftime methods, on the other hand, reference the 'strftime Behavior' section of the datetime module docs to explain the behavior of the format string. This section even notes the differences between strptime and strftime behavior.

I've tried to clear this up a little bit by renaming this section 'strftime and strptime Behavior' and referencing it from the datetime.datetime.strptime docs.

Seems reasonable.


Additionally, the block about time.strftime not utilizing date related formats (line 1514 in the patched file) can be removed. It has worked for a long time (forever?).

>>> time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
'2010-01-13 21:32:52'

I think it's referring to:

>>> datetime.time(10, 34, 6).strftime("%Y-%m-%d %H:%M:%S")
'1900-01-01 10:34:06'

and thus still applies. It is wrong about month and day being replaced by '0', however, and I've updated the patch to change that to '1'.
