here's the little script in the footer of many myphpnuke sites. i'm just a crude hacker, not a php programmer, so I can't tell if this gives you enough to work with...
echo "<center><font size=1>\n";
ss_timing_stop();
$help = sprintf(translate("Page took %s seconds to load."),ss_timing_current());
echo "$help";
echo "</font></center>\n";
echo "<br>\n";
