There's an issue with email.utils.formatdate function, illustrated here: https://gist.github.com/1321994
for reference i'm on Europe/Istanbul timezone, which is +03:00 because of DST at the time of this writing.
I'm on stable Python 2.7.2 on gentoo linux.
When I run the attached script, I get:
Fri, 28 Oct 2011 07:56:14 -0000
datetime.datetime(2011, 10, 28, 9, 56, 14, 945831, tzinfo=<UTC>)
when the local time is 12:56. so the second line is correct and first one is not.
let me know if you need any more information.
thanks for your attention.
