Hi,

I'm getting an odd result when serializing a DateTime field using XmlSerializer.

I have the following class:

public class RecordExample
        {
            [XmlElement("TheTime", DataType = "time")]
            public DateTime TheTime { get; set; }

            [XmlElement("TheDate", DataType = "date")]
            public DateTime TheDate { get; set; }


            public static bool Serialize(Stream stream, object obj, Type objType, Encoding encoding)
            {
                try
                {
                    using (var writer = XmlWriter.Create(stream, new XmlWriterSettings { Encoding = encoding }))
                    {
                        var xmlSerializer = new XmlSerializer(objType);
                        if (writer != null) xmlSerializer.Serialize(writer, obj);
                    }

                    return true;
                }
                catch (Exception)
                {
                    return false;
                }
            }
        }

When i call the use the XmlSerializer with the following testing code:

var obj = new RecordExample {TheDate = DateTime.Now.Date, TheTime = new DateTime(0001, 1, 1, 12, 00, 00)};
            var ms = new MemoryStream();

            RecordExample.Serialize(ms, obj, typeof (RecordExample), Encoding.UTF8);
            txtSource2.Text = Encoding.UTF8.GetString(ms.ToArray());

I get some strange results, here's the xml that is produced:

<?xml version="1.0" encoding="utf-8"?>
<RecordExample xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <TheTime>12:00:00.0000000+00:00</TheTime>
    <TheDate>2010-03-08</TheDate>
</RecordExample>

Any idea's how i can get the "TheTime" element to contain a time which looks more like this:

<TheTime>12:00:00.0Z</TheTime>

...as that's what i was expecting?

Thanks

Dave
