How can I make an array of times with half hour intervals?

Question

I needed a list of times like so in an array...

12am
12:30am
1:00pm
...

How can I do this with PHP?

This is maybe a more elegant way, but it requires the times to be in seconds (that also makes it more flexible).

function time_range( $start, $end, $step = 1800 ) {
    $return = array();
    for( $time = $start; $time <= $end; $time += $step )
        $return[] = date( 'g:ia', $time );
    return $return;
}
