The approach I have typically seen used is establishing call routing schedules to only send calls to the queues during the established working hours.
You could also consider looking at the Queue Metrics Interval reports. You could generate as a .XLS and then use filters in Excel to only include those intervals which are during working hours.
There is not a way to filter out specific hours from the Queues Performance view.
