title: finding out difference between two times
body: <p>I wrote the following code to determine the amount of time that employees spend on a task:</p>
  
  <pre><code>$time1 = $row_TicketRS['OpenTime'];
  $time2= $row_TicketRS['CloseTime'];
  
  $t1=strtotime($time1); 
  $t2=strtotime($time2);
  
  
  $end=strtotime(143000);  //143000 is reference to 14:30
  
  
  //$Hours =floor((($t2 - $t1)/60)/60); 
  
  $Hours = floor((($end- $t1)/60)/60);
  
  
  echo   $Hours.' Hours '; 
  </code></pre>
  
  <p>The above code is not giving me the correct time.</p>
  
  <p>For example, with a start time of 09:19:00 and end time of 11:01:00 it give me duration time of only 1 hour which is wrong.  What is the correct way?</p>
