note 107565 modified in class.mongodate by danbrown

I wanted a way to check the age of a record. This code will calculate the time between the creation date of the record, and return the seconds. I use it for caching pages similar to the max-age header in a browser. If the record is older, than my limit it deletes itself.

<?php
function microtime_diff( $start, $end=NULL ) { 
 if( !$end ) { 
 $end= microtime(); 
 } 
 list($start_usec, $start_sec) = explode(" ", $start); 
 list($end_usec, $end_sec) = explode(" ", $end); 
 $diff_sec= intval($end_sec) - intval($start_sec); 
 $diff_usec= floatval($end_usec) - floatval($start_usec); 
 return floatval( $diff_sec ) + $diff_usec; 
} 

microtime_diff($cache['stamp']->sec);
