Hi...

I have examined the code a little bit deeper, and I got a solution for these negative value problems, I think.
In my opinion it is a little bug in your hack. I figured out that my pagestarttime was always set to zero.
This is caused in global.php:

PHP Code:

if (isset($explain)) {
  $showqueries=1;
}
if (isset($showqueries)) {
  $pagestarttime=microtime();
} 


so it will only be set if showqueries is set.

I changed it to:

PHP Code:

$pagestarttime=microtime();

if (isset($explain)) {
  $showqueries=1;
}
if (isset($showqueries)) {
  $pagestarttime=microtime();
} 


so.. with this I got a start time. But there is an other little problem in functions.php.

replace this:

PHP Code:

// time format (how many digits you want to show)
  $digits=7;

  $totaltime=$endtime[0]-$starttime[0];
  $trimmedtime=number_format($totaltime,$digits);
  $percentphp=number_format(((($totaltime-$querytime)/$totaltime)*100), 2)."% PHP";
  $percentsql=number_format((($querytime/$totaltime)*100), 2)."% MySQL"; 


with

PHP Code:

// time format (how many digits you want to show)
  $digits=7;

  $totaltime=$endtime[0]-$starttime[0]+$endtime[1]-$starttime[1];
  $trimmedtime=number_format($totaltime,$digits);
  $percentphp=number_format(((($totaltime-$querytime)/$totaltime)*100), 2)."% PHP";
  $percentsql=number_format((($querytime/$totaltime)*100), 2)."% MySQL"; 


and now it should work perfectly, at least for me it does

If this may be wrong, just inform me and I edit this (but I think it should solve the problem)
