           Summary: DateTime.ParseExact adds day when parsing minvalue

When parsing an ISO 8601 date string representing DateTime.MinValue using
DateTime.ParseExact, an extra days is added to the resulting DateTime instance;
meaning you'll get 01/02/0001, instead of 01/01/0001.

To reproduce, compile and run the following code snippet using (g)mcs:

using System;
using System.Globalization;
using System.Xml;

class Program
{
        static void Main ()
        {
                const string format = "yyyy-MM-ddTHH:mm:ss.fffffffzzz";

                string d = DateTime.MinValue.ToString (format,
                        CultureInfo.InvariantCulture);
                DateTime date = DateTime.ParseExact (d, format,
                        CultureInfo.InvariantCulture);
                Console.WriteLine (date == DateTime.MinValue);
        }
}

Expected result:

True

Actual result:

False
