There is an expert parameter which allows you to output wall clock time in the output, should be useful in your case.
Code:

Wall clock time = t

CFD Solver wall clock seconds: 7.5005E+04

Here, the wall clock seconds means the required time for the solution only, or the partitioning etc is involved?
