TOU Demand is Not Upholding the Integrity of the TOU Start/End Times

When a Usage Transaction is created for the D2-Math usage rule for 60-min TOU demand and has a start time of 11:59pm and an end time a few days later at midnight, the intervals used to calculate this demand exceed the hour at which the measurement is used for.

When the logs are examined with UT intervals extracted, it can be seen that the measurement is recorded 45 minutes behind. This is problematic for TOU Demand. If On-peak demand period ends at 7pm and Off-peak demand begins after 7pm, using intervals 6:45-7:00, 7:00-7:15, 7:15-7:30, and 7:30-7:45 is dishonest as 3 of those intervals occur during off-peak hours, and should not be billed for on-peak. What is currently happening is the sum of those intervals is being used as a 7pm measurement.

Example Demand readings for a Usage Transaction that beings at 11:59pm are as follows:
11:45pm - 12:45am - recorded as 12am read
12:45am - 1:45am - recorded as 1am read
1:45am - 2:45am - recorded as 2am read

The TOU demand is not upholding the integrity of the TOU start/end times because of this and needs to be solved.

Workaround -
Force Billing to bill only at 12am
