As a user I want to be able to adjust dry weather flow diurnal profiles easily to account for day light savings
Diurnal wastewater and tradewaste profiles shift over the course of the year due to day light saving time adjustments. I would like to see ICM include the ability to phase shift the diurnal patterns to account for DLS. I believe this adjustment would be best placed in the "monthly calibration" tab where in addition to the scaling "factor' there is also a time adjustment factor

I believe this was implemented in ICMLive around 3 years ago, so should be possible in ICM.

As a toggle setting in the run settings or in a wastewater/tradewaste pattern, this would shift the diurnal patterns based on the simulation date and daylight savings time start/end dates instead of working on standard time all year long. Mathematically, this is really straightforward, but may require internal indexes (and warning messages?) for the DST start/end dates. It would also require something to turn this feature on and off as there are several areas that do not observe DST. This feature would help us more accurately predict combined sewer overflow volumes and durations where base wastewater flow has a significant influence on CSO activity.
