But that's even worse-- it doesn't give you a way to convert a naive datetime at all. Currently the only way from "2013-11-03 01:30:00" to "2013-11-03 01:30:00-0500 America/Chicago" is still datetime.replace().

Well, you are right, but at least we do have a localtime utility hidden in the email package: >>> from datetime import * >>> from email.utils import localtime >>> print(localtime(datetime.now())) 2015-04-09 15:19:12.840000-04:00 You can read <http://bugs.python.org/issue9527> for the reasons it did not make into datetime.

But that's restricted to the system time zone. Nothing good ever comes from the system time zone...
