Category: Python Library Group: Python 2.5 >Status: Closed >Resolution: Invalid Priority: 5 Private: No Submitted By: Matthias Klose (doko) Assigned to: Nobody/Anonymous (nobody) Summary: time.strftime() accepts format which time.strptime doesnt Initial Comment: [forwarded from http://bugs.debian.org/354636] time.strftime() accepts '%F %T' as format but time.strptime() doesn't, if the rule is "all what strftime accepts strptime must also" then that is bad.

But strptime is meant to be fully platform-independent for those directive documented only. Trying to support all directives for all platforms is just a practice in futility considering how many they are and how they might be implemented differently. As both directives mentioned here are not documented as supported I am closing as invalid. ---------------------------------------------------------------------- Comment By: Mark Roberts (mark-roberts) Date: 2007-01-14 16:40 Message: Logged In: YES user_id=1591633 Originator: NO For record: %F = '%Y-%m-%d' %T = '%H:%M:%S'.
