source code script for 'page created' in __ seconds ?

I was wondering if you wouldn't mind sharing the source code on how to display the "page created" / "page processed" time on the bottom of every page? I think it's a very cool feature, but have been pulling my hair out trying to code it myself....any help/advice/resources is greatly appreciated!

view plain copy to clipboard print ?

<?php
$mtime = microtime();
$mtime = explode(" ",$mtime);
$mtime = $mtime[1] + $mtime[0];
$starttime = $mtime;
?>

view plain copy to clipboard print ?

<?php
$mtime = microtime();
$mtime = explode(" ",$mtime);
$mtime = $mtime[1] + $mtime[0];
$endtime = $mtime;
$totaltime = ($endtime - $starttime);
printf("<center><font size=\"1\" face=\"Arial\" color=\"#CACACA\">Created in %f seconds.</font></center>", $totaltime);
?>

Most excellent! Thank you for taking the time to post that script. It has since made my day! -- oh, what a life I live, oh well
