No. Let's say that you have simulated n-1 time steps. Then, the mean value of a variable called U is:
The value of the previous expression is known, so the mean value of U at t=t_n is:
In fact, you do not need the values of the variables the previous time step. You only need to create a Custom Field Function/UDM to then rewrite the value at each time step.
