Route Schedues on Device dont match Basecamp?

I set up route schedules by setting the Departure and Layover times in the Route Properties window. Layover for example might be 2 hours at a location or via point.
Basecamp then estimates the Arrival time at each via point in the route which includes the layover times.
After transferring the route to the Device, the Device does not report total trip times which include the layovers. In the example above, the Device would report a total trip time of 2 hours less then Basecamp reports.
Is this how the Device should be interpreting Basecampe routes?

Thanks,
Robert
