PHP timing script

#1 my function to find out if my store is closed

function determineTime() {
$hour = date("H");
 if (($hour < '09' || $hour >= '21')) {
	return true;
} else {
	return false;
} 
} 

 

#2 my case switch to find out if the "trip" departs in less then <24 hours or <48 hours etc.....

$myDiff = dateDiff(date("m/d/Y H:i:s"), "$dep_date 05:00:00"); 
list($myHour, $myMinute) = split(',', $myDiff);
//echo $myHour.'<br/>';
//echo $myMinute;

if(!isset($myHour)) $myHour = 0;

$nowTime = date("H:i:s");
$futureTime = date("H:i:s", strtotime("$nowTime + 2 hours"));
//echo '<h1>*'.$nowTime.'*</h1>';
//echo '<h1>*'.$futureTime.'*</h1>';

//$departures = $db->query("$dep_query $dep_where $dep_order"); // NO TIME RESTRICTIONS
switch($myHour){
default:
case "":
break;

case ($myHour <= 24):
	$_SESSION['addToTotal'] = $passengers*5;

	if(determineTime()){ //we are closed
	//if the store is closed and it is TODAY do not allow the users to book a trip before 9am
		$departures = $db->query("$dep_query $dep_where AND trips.times > '09:00:00' $dep_order"); //run query

	}else{ //we are open
	//if open allow the user to book, but only for trips that are for 2 HOURS out and GREATER
		$departures = $db->query("$dep_query $dep_where AND (trips.times > '$futureTime' OR trips.times > '09:00:00') $dep_order"); //run query
	}

break;

case ($myHour > 24 && $myHour < 48):
	$_SESSION['addToTotal'] = $passengers*5;
		$departures = $db->query("$dep_query $dep_where $dep_order"); //run query
break;

}

All my times are in    H:i:s  format.

Somewhere for some reason that when we are closed users can still book trips that are for 5am.

can someone point me into a glitch they see or how i might be thinking about this incorrectly?

For glitches we need to see the full script.  Partial code does not tell us how the variables are formed, nor if they are defined at all.
