OK, we may have overlapped there. I changed XmlConvert.ToDateTime() to:

		public static DateTime ToDateTime(string s)
		{
            string format = "yyyy-MM-ddTHH:mm:sszzzzzz";
            return DateTime.ParseExact(s, format, null);
		}

and

		public static string ToString(DateTime value)
		{
			return (value.ToString("s",
CultureInfo.InvariantCulture) + 
                    value.ToString ("zzz"));
}

This makes it match the MS impl., and lets the XML [de]serialization I'm
working on work perfectly.

Cool, I just changed PuTTY and now it works perfectly. Thanks!!!!
