ASP.NET MVC model binder not parsing ISO DateTime correctly.

Question

I've been trying to post a form to my controller:

Id=0&ReportDate=2010-08-09T00%3A00%3A00&SampleText=Save

That's the XHR post that is sent, my controller picks up all the properties except ReportDate, instead setting it to the .NET epoch DateTime. Any ideas?

Edit: If I set another variable, ReportDateString, send the string to the controller and do a DateTime.Parse(), it works fine. However, I'd really like to be able to bind the DateTime directly as this feels hacky.

Edit 2: Hereis my controller code:

public void CreateTest(MyObject myObject) {
    myObjectRepository.Update(rootObject);          
}

And my object:

public class MyObject {
    public int Id { get; set; }
    public string SampleText{ get; set; }
    public DateTime ReportDate { get; set; }
}

If I set a debug, I can see that the model binder successfully binds all the properties on my post except the DateTime which it sets to the epoch date.

Edit 3: Form:

<form id="testform" method="post">
<input type="hidden" name="Id" value="0" />
<input type="hidden" name="ReportDate" value="2010-08-09T00-00-00" />
<input type="text" name="SampleText" value="Test"/>
<button id="saveButton">Save</button>
</form>

Javascript:

$('#saveButton')live('click', function(e) {
 $.post('CreateTest', $('#testform').serialize())
});

Answer 1

This works just fine for me:

 public void Test2(DateTime ReportDate, string SampleText, int Id)

with the url:

/Home/Test2?Id=0&ReportDate=2010-08-09T00:00:00&SampleText=Save

ReportDate is then {09.08.2010 00:00:00} when I break in my code...

Edit - Additional Code:

<% using (Html.BeginForm())
   { %>
    <%= Html.Hidden("ReportDate", "2010-08-09T00:00:00") %>
    <%= Html.TextBox("SampleText", "Save") %>
    <%= Html.TextBox("Id", "1") %>
    <input type="submit" />
<%} %>

I also tried the following with the same result:

<form id="testForm">
    <%= Html.Hidden("ReportDate", "2010-08-09T00:00:00") %>
    <%= Html.TextBox("SampleText", "Save") %>
    <%= Html.TextBox("Id", "1") %>
    <a href="#" id="submitform">Submit!</a>
</form>

<script type="text/javascript">
    $("#submitform").click(function () {
        $.post("/Home/Test2", $("#testForm").serialize());
    });

</script>

And this:

[HttpPost]
public ActionResult Test2(MyObject myObject) {
    return View();
}

Where MyObject is a copy/paste from your original question..
