        А если таки явно нарисовать join ?

 SELECT n_traffic.collect_time
   FROM n_logins
        JOIN n_traffic ON (n_traffic.login_id = n_logins.login_id AND
                           n_traffic.collect_time > '1970-01-01 00:00:00')
   WHERE n_logins.account_id = '1655'
   ORDER BY n_traffic.collect_time, n_traffic.login_id LIMIT 1
