DateTime to duration conversion

Does c# have support for converting two DateTime's to the xs:duration data type? (I'm assuming I need two DateTime values for this?)

References: http://www.w3.org/TR/xmlschema-2/#duration and http://www.w3schools.com/schema/schema_dtypes_date.asp (half way down)

There was support for this in the XMLConvert class as explained here: http://kennethxu.blogspot.de/2008/09/xmlserializer-doesn-serialize-timespan.html

I ended up using this code and it displays the value in the xml correct

    [XmlElementAttribute("ValidThrough", DataType = "duration")]
    [DataMember(Name = "ValidThrough")]
    [DefaultValue("P10D")]
    public string ValidThrough
    {
        get
        {
            return XmlConvert.ToString(_validThroughField);
        }
        set
        {
            _validThroughField= XmlConvert.ToTimeSpan(value);
        }
    }

    [XmlIgnore]
    public TimeSpan _validThroughField { get; set; }

TimeSpan is what you are looking for.

A TimeSpan object represents a time interval (duration of time or elapsed time) that is measured as a positive or negative number of days, hours, minutes, seconds, and fractions of a second. The TimeSpan structure can also be used to represent the time of day, but only if the time is unrelated to a particular date. Otherwise, the DateTime or DateTimeOffset structure should be used instead.

Example:

DateTime dt1 = new DateTime(2012, 10, 2, 10, 20, 00);
DateTime dt2 = DateTime.Now;

TimeSpan ts = dt1 - dt2;
