Interval Adjustment from Scalar adjusting estimated intervals inaccurately when partial day interval read is finalized and scalar read is available at midnight.

When IMD for partial day with few missing intervals is uploaded for example (08/19/2018 00:00:00 to 08/19/2018 12:00:00 PM i.e. 12 hour read) and scalar read is available at midnight (08/20/2018 00:00:00, consumption = 202KWH), interval adjustment from scalar is considering the entire scalar read consumption (202KWH) for that day instead of prorating it till 12:00PM (202/2 = 101KWH) and then adjust the intervals.
The issue can be reproduced at will with the following steps:
1. Create a device, device configuration, interval and AMR measuring components.
2. Install the device on a service point.
3. Add below regular measurements on scalar measuring component and finalize.

a. End Date Time:
08-18-2018 12:00 AM, Consumption : 0

b. End Date Time:

08-18-2018 12:00 AM to 08-19-2018 12:00 AM, Consumption : 0

c. End Date Time:

08-19-2018 12:00 AM to 08-20-2018 12:00 AM, Consumption : 202

4.Add the Interval Adjustment from Scalar VEE rule on the interval measuring component

5. Add an interval IMD for dates – 08-19-2018 12:00 AM to 08-19-2018 12:00 PM which has one missing read with condition as 201000.

6.Finalize the interval IMD. Interval Adjustment from scalar will use the scalar reads of entire date (08-19-2018 12:00 AM to 08-20-2018 12:00 AM) instead of using the reads till 12:00 PM.

The issue has the following business impact:
