WebApi - 发布错误的时间

Question

我将数据（模型）发布到api服务，发送时间正确，但接收api减去1小时，为什么会发生这种情况，我该如何解决？

准备发送请求：

[HttpPost]
public JsonResult RequestBooking(string model)
{

    var e = new BookingRequest();
    var objJavascript = new JavaScriptSerializer();

    e = objJavascript.Deserialize<BookingRequest>(model);
    //e.AppointmentDate = 21/09/2016 13:00:00
    string addressRoute = "api.domain.com/Booking/Post";
    using (var booking = new HttpClient())
    {
        booking.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        var response = booking.PostAsync(addressRoute, new StringContent(new JavaScriptSerializer().Serialize(e), Encoding.UTF8, "application/json")).Result;
        return Json(response, JsonRequestBehavior.AllowGet);
    }
}

收到：

public HttpResponseMessage PostRequest(DomainObjects.BookingRequest request)
{
     //request.Appointment = 21/09/2016 12:00:00 <----
}
