I did update the chatbox.php earlier.

Holy macaroni! I got it working!
Changed the following:

     if ($tagarounduser) {
        $tagopen = "<$tagarounduser>";
        $tagclose = "</$tagarounduser>";
    }

To:

    if ($tagarounduser) {
        $tagopen = "<span title=\"$time\"><$tagarounduser>";
        $tagclose = "</$tagarounduser></span>";
    }

And the following from:

    echo "\n".'<span id="shout'.$shout['shoutid'].'">['.$time.'] '.$tagopen.$username.$del."$tagclose: ".$parsed.'<br /></span>';

To:

    echo "\n".'<span id="shout'.$shout['shoutid'].'"> '.$tagopen.$username.$del."$tagclose: ".$parsed.'<br /></span>';

So now the time of the message is only shown when holding the mouse over the username. I'm happy!
