Converting a date such as 1/21/2008 11:09:05 AM to XML Date/Time Format.
You might want to put this code into a MapHelper library, then reference
it from a Scripting Functoid in a BizTalk Map.

<code>
        public static string ConvertDateTimetoXmlDateTime(string inDate)
        {
            try
            {
                DateTime dtIn = DateTime.Parse(inDate);
                return System.Xml.XmlConvert.ToString(dtIn, System.Xml.XmlDateTimeSerializationMode.Local);

            }
            catch
            {
                return "invalid-Date/Time-conversion from value='" + inDate + "'";
            }
        }
</code>
