I noticed that many string[] properties in DateTimeFormatInfo are
used directly in DateTime. They have to return Clone() which are
not neccessary there.

using System;
using System.Globalization;

class Test
        public static void Main ()
                for (int i = 0; i < 1000; i++)
                        DateTime.Parse ("2006-11-30T01:01:01.000");

Before the patch:
Total memory allocated: 378 KB

After the patch:
Total memory allocated: 292 KB

If it does not look harmful, I'll commit later.
