[Patch] url-cache: wrong time in If-modified-since header

[Diane Murray]

`url-get-normalized-date' returns the local timezone's time yet states
that GMT is the timezone.  For example, when CEST is the local
timezone, "20 Sep 2007 01:19:04 GMT" gets sent to the server instead
of "19 Sep 2007 23:19:04 GMT".  This prevents URL from making proper
use of the cache.  The patch below fixes this.


2007-09-20  Diane Murray  <address@hidden>

        * url-util.el (url-get-normalized-date): Fixed to return the
        correct time when the local timezone isn't GMT.
