Time step choice

I have one question about the choice of time step in COMSOL 4.4. I tried to run a simulation twice on the same machine and in batch mode (so I used the same input file, but indicated two different output files) and I noticed that between the two simulations there is a (tiny) difference in the number of performed time steps, as sometimes the time steps have different lengths. I am sure they are really the same simulation.
I was quite surprised by this behavior and I am very curious about the reason. Does anyone know the reason?
