Posts recent buzz's you've made to google buzz!
In order to theme it you have to add styling yourself. An example can be found in the comments at: http://www.fieldjournal.co.uk/?p=189&cpage=1#comment-256
Modify the $TIMEZONE constant to the appropriate timezone! A list of time zones can be found at: http://php.net/manual/en/timezones.php For example if I'm in Dubai and my recent buzz says it was posted 4 hours ago, I'd use $TIMEZONE='Europe/London'; as London is 4 hours behind. Therefore changing it to x minutes ago.
