WP Post Ratings Time Range for Highest Ratings

Hi,

I’m using the WP-PostRatings plugin and I’m trying to make something like a “Highest Rated For This Week” feature. Is there a way to do this, by limiting the highest rated ones displayed to only the past week? Or past month, or whatever.

I looked around and this seemed like it might be useful:

<?php if (function_exists(‘get_highest_rated’)): ?>

<?php
$mylimit=7*(60*60*24);
if ( (current_time(timestamp) – get_the_time(‘U’) – (get_settings(‘gmt_offset’) * 3600) ) < $mylimit)
{ ?>
<?php get_highest_rated(‘post’, 5); ?>
<?php } ?>

<?php endif; ?>

I found that edit for another function on some other thread, and thought it might work, but it’s not working for some reason.

Any help is greatly appreciated ?? Thanks
