here is a very unpolished, very bloated script to reverse a timestamp and convert it to a readable
date in two ways

$yearnow = $yearnow + 4;
}
//now see if its a leapyear
$lycheck = $yearnow / 4;
$lycheckr = round($yearnow / 4,0);
//if they are the same, it is a leap year and we have to add the extra day
while ($timeleft >= $leapyear){

left.
