[Plugin: Folding Category List (FoCaL)] post count incorrect due to date stamp

Folding Category List displays correct post counts for only a few of my categories and the others show up as 0 regardless of the actual post count. I examined the file focal_wp28.php and found the problem is related to the following SQL that selects a the posts for a given category:

$querystr = "
  			SELECT DISTINCT $wpdb->posts.ID
  			FROM $wpdb->term_taxonomy, $wpdb->posts, $wpdb->term_relationships
  			WHERE $wpdb->posts.ID = $wpdb->term_relationships.object_id
  			AND $wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id
  			AND $wpdb->term_taxonomy.term_id = $cat->term_id
  			AND $wpdb->posts.post_status = 'publish'
  			AND $wpdb->posts.post_type = 'post'
  			AND $wpdb->posts.post_date < NOW()
  		";

If I remove the last bit that checks the time stamp (posts.post_date) then everything works fine. I checked the time stamps on my posts and the ones not being included have time stamps for today.

My best guess is that the time stamp in the database has a different time zone than what’s returned by NOW().

Is this an issue with my WordPress database or is there a different way to check the time stamp?

Thanks
