Hi

On line 28 of rss_utils, under the function parse_w3cdtf, there's this regular
expression
$pat =
"/(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2})(:(\d{2}))?(?:([-+])(\d{2}):?(\d{2})|(Z\
))?/";

It should match the ISO 8601 date format (ex: 2005-07-26T12:16:26+02:00)

However, the parenthesis are wrong for the matching seconds. This way it will
produce a
":26" instead of the desired "26"

This of course makes the next function gmmktime fail.

You should fix the regular expression and keep the : out. Should be an easy fix.
