about the time discretization openfoam

Dear All,

I have a question about the time discretization in the OpenFOAM. As you know, for time discretization, we always need to the quantities (like rho, U) from the current time step and previous step. In the time loop, we always need to update the quantities after the new quantity is calculated for the current time step. In openfoam, which is this implemented for the update of these quantities?

best regards,
OFFO
