HTML5's HTMLInputElement IDL has
>          attribute Date valueAsDate;

We need to support binding for Date.

Proposed patch

Generated code for "Date valueAsDate setter raises(DOMException)" will be like:

  static v8::Handle<v8::Value> valueAsDateAttrGetter(v8::Local<v8::String> name, const v8::AccessorInfo& info) {
    INC_STATS("DOM.HTMLInputElement.valueAsDate._get");
    v8::Handle<v8::Object> holder = info.Holder();
    HTMLInputElement* imp = v8DOMWrapperToNode<HTMLInputElement>(info);
    double v = imp->valueAsDate();
    if (isnan(v) || isinf(v))
        return v8::Null();
    else
        return v8::Date::New(v);
  }

  static void valueAsDateAttrSetter(v8::Local<v8::String> name, v8::Local<v8::Value> value, const v8::AccessorInfo& info) {
    INC_STATS("DOM.HTMLInputElement.valueAsDate._set");
    v8::Handle<v8::Object> holder = info.Holder();
    HTMLInputElement* imp = v8DOMWrapperToNode<HTMLInputElement>(info);
    double v = value->IsDate() ? value->NumberValue() : std::numeric_limits<double>::quiet_NaN();
    ExceptionCode ec = 0;
    imp->setValueAsDate(v, ec);
    if (UNLIKELY(ec))
        V8Proxy::setDOMException(ec);
    return;
  }

This looks fine.  Please update the FIXME to match the patch:

"FIXME: Add Date support for V8, Objective-C, and COM."
