Listings Today's Events but Past Events Still Appear

I’m using the em_events template tag to display a list of events that occurred today from a certain category. Here’s my code:

<?php em_events (array( 'scope' => 'today',
										'category' => array(12),
										'limit' => 5,
										'orderby' => 'event_start_time')); ?>

The problem, though, is that it’s still showing events that appeared earlier in the day, which I don’t want. I want those events to drop off automatically as the day progresses.

Does anyone have any suggestions?
