look here:
https://github.com/plone/plone.app.event/blob/master/plone/app/event/dx/behaviors.py#L341


ok, if i recall all the decisions again, and IIRC, the necessity of
setter/getter can maybe resolved...

the widget returns a datetime object timezone-naively. the start/end
setter of EventBasic applies a FakeZone, because on the context there
might be already a timezone-aware start/end date (if the event is beeing
edited instead of created). so, if we hadn't the FakeZone applied, in
case of editing an event, some z3c.form validator or something compares
the timezone-naive value from the widget to the timezone-aware value
from the context and throws an error. timezone-naive dt cannot be
compared to timezone-aware ones...
