Rework the logic for handling the date timezone and converting from and to the db storage timezone. Finally realized the widget cannot do the timezone transformation, the widget must always be handling a date in the same timezone so validation and other processes can work correctly no matter what route the form takes. It will be up to the field, not the element, to transform the date from gmt to the local timezone when the date is retrieved from storage and back again before saving it.

This is the first of a series of updates to get this change implemented. Things are likely to be buggy untill all these changes are reworked and committed.
