"RANS" means "Reynolds-Averaged Navier-Stokes", and Reynolds-Averaging is a form of time averaging. So if you solve the RANS equations, then you're solving a time-averaged form of the equations.
This time-averaging has nothing to do with the solver you are using. If you use the unsteady solver, then you are marching in time and solving time-accurately. If you use the steady-state solver, then you are still marching in time until you get to steady-state, but not solving time-accurately.
