Issue:

In the Microsoft Project (MSP) new driver, work hours hours change in the Timescale in a round trip save for a resource if their calendar shifts are not set to 8 hours per day. 

Steps to Reproduce: 
1. Create a new resource in PPM 
2. Update the resource's shifts to make their availability 7.5 hours: 
a. Go to Home->Resources, click on the resource created and then click on the Calendar tab 
b. Select the check box next to Mon, Tue, Wed, Thu, and Fri 
c. Click the 'Set Shifts' button 
d. Make Shift 1: 08:00 AM - 12:00 PM and Shift 2 01:00 PM - 04:30 PM and click 'Save and Return' 
3. Create a project in PPM 
4. Add the resource created in step 1 to the Team 
5. From the Task or Properties tab, select ‘Open in Scheduler’ -> ‘Microsoft Project [Read-Write]’ to open the project in MSP 
6. Go to the Task Usage view (View used is monthly) 
7. Create 1 new task 
8. Assign the resource to the task with the following hours: 
Assign 80 hours of work for the resource for February, March, and April 
9. Save the project back to PPM 
10. Open the project from PPM to MSP and navigate back to the Task Usage View
