Roy Smith added the comment: I see I mis-stated my example. When I wrote:
s = str(d1) d2 = datetime.datetime(s) assert d1 == d2 what I really meant was: s = d1.isoformat() d2 = datetime.datetime(s) assert d1 == d2 But, now I realize that while that is certainly an absolute lower bound, it's almost certainly not sufficient. The most common use case I see on a daily basis is parsing strings that look like "2012-09-07T23:59:59+00:00". This is also John Nagle's original use case from the cited mailing list thread: > I want to parse standard ISO date/time strings such as > 2012-09-09T18:00:00-07:00 Datetime.isoformat() returns something that matches the beginning of that, but doesn't have the time zone offset. And it's the offset that makes strptime() not usable as a soluation, because "%z" isn't portable. If we don't satisfy the "2012-09-07T23:59:59+00:00" case, then we won't have really done anything useful. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15873> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
