This is an old thread, but use BETWEEN. This is an excerpt from my timeclock, pls modify to your needs...

$qs = "SELECT COUNT(*) AS `count` FROM `timeclock` WHERE `userid` = :userid 
                AND (
                    (`timein` BETWEEN :timein AND :timeout OR `timeout` BETWEEN :timein AND :timeout )
                    OR
                    (:timein BETWEEN `timein` AND `timeout` OR :timeout BETWEEN `timein` AND `timeout`)
                    );";
