Hi,
I am making a counting system, which will told visitor to a days difference within selected date range.

If user enter date till 2038 it works fine..and user enter beyond then this, then it start giving error (negative values)

I read that due to PHP version problem it did, but we have "PHP Version 5.2.5" installed on the server.

Can you please suggest about this error.

For your reference, i am using following code:

$dateDiff = mktime( $from['hour']  , $from['minutes'] , $from['seconds'] , 
                        $from['month'] , $from['day']     , $from['year'] ) -
                mktime( $to['hour']    , $to['minutes']   , $to['seconds'] ,
                        $to['month']   , $to['day']       , $to['year'] );

	$intDays    = floor(  $dateDiff / (60*60*24) );

    $intHours   = floor( ($dateDiff - ($intDays*60*60*24) ) / (60*60) );

    $intMinutes = floor( ($dateDiff - ($intDays*60*60*24) - ($intHours*60*60) ) /60 );
