Subject: guix download error "Bad Date header"
Date: Thu,  2 Jul 2015 10:48:33 +0200 (CEST)

Hi,

guix download doesn't seem to like date headers that don't use GMT / UTC.  #guix irc logs from 2013-10-16 mention something similar.  Any suggestions or work-arounds?

Below is some relevant output -- first with guix download, then with wget -S (note the Expires header):

Hi,

I believe the HTTP ‘Date’ header parsing issue was fixed in Guile
commits b9f6e89a271c04741231b64b03fe7fc294723f1d and
8904b7a9362ede0de324e55701d8ea1d018f8738.

The example given in this bug report now passes:
