Wordpress All-In-One Event Calendar: Show Upcoming Events Only
===

I'm using the All-In-One Event Calendar found here: http://wordpress.org/extend/plugins/all-in-one-event-calendar/ <br/>
I'm trying to display upcoming events only (so no past events) using the WP_Query() function. I see there is a <em>"wp_ai1ec_events"</em> table in the database and a column named <em>"start"</em> with the start times in yyyy-mm-dd hh:mm:ss format. I can get the current time in the same format using <em>$currentTime = current_time('mysql')</em>

This is what my query looks like so far: 
   

        $frontpageevents='post_type=ai1ec_event&showposts=3&orderby=start&order=ASC&meta_value=yes';
    $eventquery = new WP_Query($frontpageevents);

I've tried adding '&start>'.$currentTime to the end of the $frontpageevents declaration, but that didn't work. I was hoping if someone knew how to handle this.
