Schedule: Events by time and then by date

The following theme snippet allows me to highlight the schedule per time slot, instead of per date. The attached screenshot gives an example of what I needed to achieve.

WARNING: This is for REFERENCE purposes only to demonstrate the feature that I needed to implement. It should NOT BE USED as it is FLAKY and REQUIRES PERFECTION in how the repeating events are added. If you know of a way to build a scheduling system (where people can sign up for time slots on each date/time) without using ridiculous hacks, please leave your comments and let me know how! Thanks. :)

 function THEMENAME_event_node_week($node) {
 ...
 // at the end of this function the following 'tag' is added:
$output .= "BREAKFORROWS";

And then the table is rebuilt using rows for time slots instead of just all events in one day shoved into a column.

 // Build the table for the WEEKLY view
function THEMENAME_event_calendar_week($op, $header, $rows, $attributes = array(), $caption = NULL) {
	// a whole week is stored as one row
	$wholeweek = $rows[0];
	unset($rows);
	
	// for each day, break out the time slots	
	for ($i=0; $i < count($wholeweek); $i++) {
		$event[$i]['class'] = $wholeweek[$i]['class']; 
		$event[$i]['id'] = $wholeweek[$i]['id']; 
		$day = $wholeweek[$i]['data'];

		// each day contains several time slots
		$events = explode("BREAKFORROWS", $day);
		$dropempty = array_pop($events);

		for ($j=0; $j < count($events); $j++) {
			$rows[$j]['data'][$i] = $events[$j];

			if ($i < 1) {
			$rows[$j]['class'] = $event[$i]['class'];
			$rows[$j]['id'] = "timeslot-$j";
			}
		}
	}
	
	$output = theme("table", $header, $rows, $attributes, $caption);
    return '<div class="event-calendar"><div class="week-view">'. $output ."</div></div>\n";
}
