Estimation batch (D1-SMMTR) is creating non-midnight reads (10 PM reads) when the period includes two DST transitions and the batch run date is in DST.
Ex: Period is from Nov 1st 2016 to Mar 14th 2017.
There are 2 DST transitions for this period: Nov 6th 1:59:59 2016 and March 12th 1:59:59 2017.


Steps to Recreate
1. Create a device, device configuration and install it on a service point.
2. Create a set read for the measuring component on 11/04/2016 12:00AM.
3. Run batch in DST (suggested March 14, 2017 onwards).
4. Non midnight estimation happens during an estimation batch run at DST trying to estimate missing reads in which DST end was included. 

Sample: Estimation Batch Run: March 14, 2017

Missing Reads to be estimated: 11/05/2016 to 11/14/2016 10 PM estimation will start at DST end 11/06/2016
