so i should add this function to class.tslib_fe.php too?
(Whats about the naming?)

function setPageCacheExpiresTimestamp($timestamp) {
        if ($timestamp != 0 && $timestamp < $this->cacheExpires) {
                $this->cacheExpires = $timestamp;
        }
}
 
and if that would be the right way, how would it be documented?

thanks,
