Hi all,

I finally got annoyed enough to debug a problem with the timezone field
in the .ics export of my agenda.

Turns out the problem was simple: org-icalendar--vcalendar was being
called with the wrong argument order in
org-icalendar-export-current-agenda, so the timezone was going into the
description field rather than the timezone field.

Here's a patch that fixes that.  Note that it should be applied to
maint.  I did not generate a commit against master, but I can if need
be.

Best,
Richard
