The applixure account administrator should be able to specify one or more user defined daytime periods to calculate and report device utilization percentages in addition to out-of-the-box ones, for example a "office hours utilization" (08:00 am to 16:00 pm), a "morning utilization" (08:00 am to 11:59 am) and a "afternoon utilization" (12:00 pm to 16:00 pm). By this way it would be better to evaluate the actual device usage between the specified user defined daytime periods.
