Ordering by multiple meta keys – Custom post type

Why don’t store date and kickoff time in the same datetime field and sort it by this meta value?

Please, note that you may need change this:

$args = array(
        .......
        'orderby' => 'meta_value',
         .........
    );

To:

$args = array(
        .......
        'orderby' => 'meta_value_num',
         .........
    );
