Answer 1

I wrote a code for you that you can modify the difference of days between departure and arrival.But but but this code is only and only for a single time zone.If you have different times in different time zones that's different!

<?php
/**/
$Departure_Time='05:20';//Set Departure time
$Arrival_Time='18:30';//Set Arrival time
$dayDifference=0;//You can modify this 
/**/
$a=strtotime($Departure_Time);
$b=strtotime($Arrival_Time.' + '.($dayDifference*24).' Hours');
$interval = ($b - $a) / 60;
$traveltime=date("i:s",$interval);
echo $traveltime;
?>

And I really don't have any ideas why did I use i:s for hour and minute!

But anyway it works!

Tell me if you have any problem with the code :)
