Self.dt does not match with the actual step time

Hi,

for instance I set self.dt = 1/60.in the example script “cartpole.py” and compared the time with the output from print (" time spent for each step ",self.gym.get_elapsed_time(self.sim)). I expected something around 1/60= 0.0166, however varies from 0.01s-0.02s.
Is this because the python scripts are not deterministic?
