Because most of the time is typically spent in "electrons". Anyway: the
script is provided because it is available, but you may simply run the four
input data (test_[1-4].in) and look at the total time spent in the run (the
one reprinted at the end of the run, that should be more or less the same
given by system tools like "time", or in reports of the queueing systems)
