Date sorting in Verve Meta Boxes

Our site has an upcoming events box that pulls in post titles as the upcoming events with Location and Date/Time info pulled in via boxes created using Verve Meta Boxes. I couldn’t use the Date field type for the date info, as it doesn’t support date ranges but only single dates. So, we set up the Date/Time field as a text entry. Doing so makes the post date the date used for sorting the events instead of the event date. I’m wondering if I could set all post dates to the event dates, and have even the ones set in the future appear in the list?

Here’s the code:

<table id="ma_events">
	<tr class="toprow"><td class="details">Details</td><td class="location">Location</td><td class="date_time">Date/Time</td></tr>
	<?php
		$temp = $event_query;  // assign orginal query to temp variable for later use
		$event_query = null;
		$event_query = new WP_Query('cat=25,20&posts_per_page=5&orderby=date&order=asc');
		if(have_posts()) :
			while($event_query->have_posts()) : $event_query->the_post();
	?>
	<tr class="eventrow">
		<td><a>" rel="bookmark" title="Read more — <?php the_title_attribute(); ?>"><?php the_title(); ?></a></td>
		<td><?php echo get_post_meta($post->ID, 'location', true); ?></td>
		<td><?php echo get_post_meta($post->ID, 'date_time', true); ?></td>
	</tr>
	<?php
		endwhile;
		endif;
		$event_query = $temp;  //reset back to original query
	?>
</table>

Thanks!
