===============================
                     120 minutes + 24 hours ( one day ) / 60x24 = 1440 minutes
                     = 1560 minutes x 60 + 20 seconds

Answer 1

Use the DateTime class. Note that diff() is a >= PHP 5.3 method. If you have an older version, you can always use strtotime().

$dateStart = new DateTime('Thu, 26 May 2011 11:40:00 +0000');

$dateFinish = new DateTime('Thu, 25 May 2011 11:39:40 +0000');

echo $dateStart->diff($dateFinish)->s; // 20
