title: Rubygems Chronic cannot parse "2010-09-12 3:12pm" but can parse "2010-09-12 3pm" or "last monday 3:12pm"?
body: <p>It seems strange that "2010--9-12 3:12pm" is a weak spot of Chronic Rubygem?  Is there a way to make it work?  (or another gem that can do it?)  I also hope to find a parser that can handle <code>2010-09-12 3:12pm UTC</code> or other timezones such as <code>PDT</code>, <code>PST</code>, or <code>UTC+8</code> or <code>-0700</code></p>
