Timescaledata Start Date and Finish Date not both inclusive

Question

From testing a bit with Time Scale Values in Visual Basic I noticed that when specifying Start and Finish dates for accessing Time Scale Data those dates were not both inclusive. The fact is that specifying a Start Date for Time Scale values will return
data for which dates are greater or equal to the Start Date Specified but when also specifying a Finish Date the Time Scale values returned are only the ones that are less than the Finish Date specified not the ones less or equal as one would expect since
the Start date is Incllusive. This is true for actual work with Microsoft Project 2007 and 2013 unsing Visual studio 2013. Has anyone experienced such a behavior? Is this a intended Behavior? Please see following code snippet

Jaques,
In my example, the ass.start and ass.finish are the start and finish dates respectively of the assignment. Since the resource is assigned full time for the whole duration of the task, the assignment start and finish are the same as the task start and finish,
namely, Dec 1, 2014 and Dec 7, 2014. If you only want data for specific days, say Dec 4, 2014 and Dec 5, 2014, then the syntax would be:
Set TSV = ass.TimeScaleData("12/4/14", "12/5/14", pjAssignmentTimescaledWork, pjTimescaleDays)
The result will be 7h and 8h respectively.
If you want to print out the date along with the hours for each day in the Immediate Window, the following modification to the macro will do that:
Sub testtimescale()
Dim ass As Assignment
Dim TSV As TimeScaleValues
Dim val As TimeScaleValue
Dim i As Integer
Dim Da As Date, St As Date, Fi As Date
For Each ass In ActiveProject.Tasks(1).Resources(1).Assignments
    St = ass.Start: Fi = ass.Finish
    Set TSV = ass.TimeScaleData(St, Fi, _
        pjAssignmentTimescaledWork, pjTimescaleDays)
        Da = DateValue(St)
    For Each val In TSV
        Debug.Print Da & " " & val / 60 & " hours"
        Da = DateValue(Da + 1)
    Next val
Next ass
End Sub
