Edited Issue: EditorFor converts DateTimeOffset property to text type instead of datetime type [1442]

Model
public class MyModel
{
public int MyModelId { get; set; }
public DateTime DateTime1 { get; set; }
public DateTimeOffset DateTimeOffset1 { get; set; }
}

I scaffolded mvc5 controller and view. On F5, page source shows DateTime1 with type = "datetime" but DateTimeOffset1 with type="text"

<input class="form-control text-box single-line" data-val="true" data-val-date="The field DateTime1 must be a date." data-val-required="The DateTime1 field is required." id="DateTime1" name="DateTime1" type="datetime" value="2013-11-21T00:00:00.000-08:00" />

<input class="form-control text-box single-line" data-val="true" data-val-required="The DateTimeOffset1 field is required." id="DateTimeOffset1" name="DateTimeOffset1" type="text" value="11/12/2012 1:05:20 AM +00:00" />
