 explain why those date/time strings needs to be fixed for every
 culture. Until this is done, I set the priority as wishlist.

 Moreover, the list does not show the fact. For example, we Japanese
 never use '?' for date and time.

+So you're actually saying that for other patterns there are 
+mismatches between Mono and MS.NET too ? I can't see what the 
+purpose of that would be.
+
+Is compatibility and interoperability with MS.NET not a goal here ?
+
+What's the benefit of deliberately introducing interoperability 
+issues ?
+
+That aside, the FullDateTimePattern for most cultures is just plain 
+wrong, and results in a datetime string that is not parsable.
+
+Try running the following code snippet on Mono:
+
+CultureInfo cultureJp = new CultureInfo ("en-US");
+string date = DateTime.Now.ToString ("F", cultureJp);
+Console.WriteLine(date);
+DateTime.Parse (date, cultureJp);
+
+Actual result:
