Timezone isn't passed in event link to view details on google.com/calendar

When linking to an event's details the time is displayed in GMT instead of my specified timezone.
I looked in the api and &ctz=".$timezone is required if you want to specify the timezone or google defaults to gmt.
So to test a fix I added that to the link ($item['link']) in the gcal_events module. Roughly around line 743 (I still have my fixes in there overriding simplepie's removal of futureevents=true).

			if ($item['link']) {
/*-*/					$temp_event=str_replace("#URL#", $item['link'], str_replace("#URL#", variable_get('gcal_events_template_url_'. $which_block, 
/*+*/				$temp_event=str_replace("#URL#", $item['link']."&ctz=".$timezone, str_replace("#URL#", variable_get('gcal_events_template_url_'. $which_block, GCAL_EVENTS_DEFAULT_TEMPLATE_URL), $temp_event));
			}
			else {
				$temp_event=str_replace("#URL#", "", $temp_event);
			}

Now the events are all displayed in the event's timezone on google, just as they are on the site.
