function publish_later_on_feed($where) {
global $wpdb;
 
if ( is_feed() ) {
// timestamp in WP-format
$now = gmdate('Y-m-d H:i:s');
 
// value for wait; + device
$wait = '5'; // integer
 
// http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_timestampdiff
$device = 'MINUTE'; //MINUTE, HOUR, DAY, WEEK, MONTH, YEAR
 
// add SQL-sytax to default $where
$where .= " AND TIMESTAMPDIFF($device, $wpdb->posts.post_date_gmt, '$now') > $wait ";
}
return $where;
}
 
add_filter('posts_where', 'publish_later_on_feed');

Increase or Decrease update delay:
In the above code find $wait = ’5′; // integer and change 5 to anything you like. If you want to increase more than an hour find $device = ‘MINUTE’; and change it to MINUTE, HOUR, DAY, WEEK, MONTH or YEAR.
