+It appears the ToString(string format) method does not contain a
+definition to handle 'o' in the internal static string
+_GetStandardPattern (char format, DateTimeFormatInfo dfi, out bool
+useutc, out bool use_invariant) method.
+
+
+ case 'O':
+ case 'o':
+    return "yyyy'-'MM'-'dd'T'HH':'mm':'ss.fffffffK";
+
+
+since this is happening the default: pattern = null; break; is hit. 
+In the Microsoft documentation there is the definition for 'o' and in
+their  DateTime example it contains the following lines.
+
+Console.WriteLine(msgRoundtripLocal       &       
+thisDate.ToString("o"), ci)
+        Console.WriteLine(msgRoundtripUTC         &        
+utcDate.ToString("o"), ci)
+        Console.WriteLine(msgRoundtripUnspecified &
+unspecifiedDate.ToString("o"), ci)
