Can I make a clock that starts off the same as the server time, but then runs twice as fast as a clock in reality? Also it would have to print the data onto a page.

sure why not,

<html>
<head>
<script type="text/javascript">
var timer = null

<?PHP
$now=getdate();
echo "var hours = ".$now['hours']."\n";
echo "var minutes = ".$now['minutes']."\n";
echo "var seconds = ".$now['seconds']."\n";
?>
function start_clock()
{
timer = setTimeout("update_clock()",1000)
}

function stop_clock()
{
clearTimeout(timer)
}

function update_clock()
{
  if (seconds < 59)
    seconds++
  else
  {
    seconds=0
    if (minutes < 59)
       minutes++
    else
    {
      minutes=0
      if (hours < 12)
        hours++
      else
        hours=1
    }
  }
document.forms["clock"].display.value = hours + ":" + ((minutes < 10) ? "0" : "") + minutes + ":" + ((seconds < 10) ? "0" : "") + seconds
timer = setTimeout("update_clock()",1000) //********* change this to 500 to make the clock run twice as fast
}
</script>
</head>
<body onload="start_clock()" onunload="stop_clock()">
<form name="clock">
<input type="text" name="display" size="10">
</form>
