Let's setup all required adapters using zcml. This makes sure we test
the real configuration. Let's render the widgets in different
modes and try to extract the value form an request.

  >>> import datetime
  >>> import z3c.form
  >>> import zope.schema


12 o'clock
----------

Test widgets 12 o'clock PM. (12h (noon) is 12 PM wenn using AM/PM, 24h/0h is
12 AM).

  >>> field = zope.schema.Datetime(default=datetime.datetime(2007, 4, 1, 12))
  >>> widget = self.setupWidget(field)
  >>> widget.update()
  >>> widget.extract() is z3c.form.interfaces.NOVALUE
  True


INPUT_MODE

Render without AM/PM support:

  >>> widget.ampm = False
  >>> widget.mode == z3c.form.interfaces.INPUT_MODE
  True
  >>> print widget.render()
