If you change the timestep, you'll get a discontinuity in the trajectory, 
and in the energies.

But you were referring to different timestep giving different temperature 
right? Please check that other parameters (expressed in timesteps) keep 
their same value in fs, in particular nstlist (neighbourlist update).

Maybe we should change these variables to time instead of steps...
