Wanted: Service I need help with some code, please!

[Spider]

I am running a script on thugrater.com that uses cached info that is updated every hour. The readme.txt says I can update a specific line of code to make it update faster. Can someone tell me what to update? This is the code below and I have no idea how I can make it faster, I would rather it update everytime a user comes to the site or maybe every minute....

if(@filemtime($file) < mktime(date("H")-1, abs(date("i")), abs(date("s")), date("m"), date("d"), date("Y"))){

$output = <<<FO

This would do it every minute

if(@filemtime($file) < mktime(date("H"), abs(date("i")-1), abs(date("s")), date("m"), date("d"), date("Y"))){

$output = <<<FO
