R. David Murray added the comment: Right, that's why I said "if it is a bug" :) FreeBSD has the same behavior, so I'd actually prefer that Apple not "fix" this. It would be nice if FreeBSD did and Apple adopted it, though, since only dropping the % is the least intuitive approach to handling

R. David Murray added the comment: But if it is a bug, it is a bug in OS/X, not in Python. Python could potentially fix it for python programs by providing our own strftime, but until someone does that the best we can do is a doc mention of this platform quirk. -- __

R. David Murray added the comment: Python's strftime is a thin wrapper around the system strftime. This means, for example, that a slightly different set of % codes is supported on windows vs linux. So, from Python's point of view this is at *most* a doc bug. That said, I think there have b

[issue9811] strftime strips '%' from unknown format codes on OS X

New submission from Sverre Johansen : There seems to be a platform difference in the way stftime handles unknown format codes. In OSX Python removes the percentage sign from the returned string when the format code is unknown. In Linux it leaves it. Look at the following example: This is Pyt
