Dear Materials studio community

I have a very small question to make sure about my MS 2016 installation. Is it possible that the total time that dmol3 reports as the calculation time (at the end of report or beside the scf iterations) be very different with the real job runtime (the time of execution/end of the job - the time at which the job starts). The difference in my cases is very considerable, i.e the Dmol3 reported time is 2-3 times lower.

Thank you
