DateTime field offset and local time

I would want to use DateTime offset set to local timezone, this way all the date string can be viewed in admin ui as local date time rather than UTC.

possible improvements.

Start by locating the DateTime field implementation and the admin UI date rendering described in the issue. Determine how timezone offsets are currently handled and define what local-time display should mean for date strings. Done means the requested local-time behavior is specified and implemented consistently in the admin UI.
