In counties where it is decided that daylight savings time will not be implemented any more, various issues can appear while using MUX.
1) When trying to edit cells for some cost plans receiving error: TSV type attribute 'cost' cannot have segment dates beyond the curve start or finish dates.
The period falls within the dates of the cost plan.
2) In some instances, when an attribute is a date attribute and the date chosen is between the dates when DST used to be, the day will subtract hour in the UI and the database, stetting the day back one day in the UI.
