The timezone-handling in [346] is still too naive: according to http://www.cl.cam.ac.uk/~mgk25/iso-time.html, timezones can be specified in any of the following forms:
+hh
+hhmm
+hh:mm
-hh
-hhmm
-hh:mm
I propose the following patch, which can deal with any of these forms. It also saves the timezone data; although we don't currently use it for anything, this patch will make a good jumping-off point in the future if we decide to use it.
