When the Torrus Reporting engine is set up, this command is used to
combine several services data into a new service ID. The output data is
either the maximum or the sum of input services.

--start=YYYY-MM-DD

Instead of setting the end data, it is convenient to use this
option. It sets the end data in one calendar month after the start
date.
