PHP

        public function is_utc_timestamp($timestamp){
            //If the timestamp contains any non-digit
            if ( preg_match('/\D/i', $timestamp) ){
                return false;
            }

            //If the timestamp is greater than May 18, 2033 (This function only supports up to this date to avoid conflicts with phone numbers. We'll have to figure out a new solution then.)
            if ( strlen($timestamp) === 10 && substr($timestamp, 0, 1) > 1 ){
                return false;
            }

            //If the timestamp has between 8 and 10 characters.
            if ( strlen($timestamp) >= 8 && strlen($timestamp) <= 10 ){
