Re: subtracting time from date and time

Something like this will get it into a time stamp...and then you can do your calculations with ease, and reformat... <?php

       $str = "20070617T193500";
       list($date, $time) = explode("T",$str);

       $year = substr($date, 0, 4);
       $mon = substr($date, 4, 2);
       $day = substr($date, 6,2);
       echo "$year - $mon - $day\n";

       $h = substr($time, 0, 2);
       $m = substr($time, 2, 2);
       $s = substr($time, 4,2);
       echo "$h : $m: $s\n";

       $ts = mktime($h,$m,$s,$mon,$day,$year);
