It computes this integral at a single time step, although if you want to time-average you can certainly do that yourself. However, if you use complex fields (set! force-complex-fields? true), and have a single-frequency (CW) field, then |E|^2 is proportional to the time average and hence V evaluated at a single timestep is equal to the time average.
