Timezone is wrong

You have a problem in your adrotate_date_start function, it leaves the website timezone as UTC instead of what it is set in WordPress. So any widget/plugin etc that is fired after your plugin will result in the timezone being wrong.

So to fix this at the end of the widget function I added this to return the site back to the proper timezone.

$timezone = get_option(‘timezone_string’);
if($timezone) date_default_timezone_set($timezone);
