Describe the expected results

Shortly, when I use DateTimeField with a DateTimePickerWidget I see only the calendar tool and not the time picker as you can see in the attached image.

add_form_extra_fields = {
        'contract_date': DateTimeField('Contract Date', default=datetime.today, validators=[DataRequired()],
                                       widget=DateTimePickerWidget())
    }
