Thanks for the chapter and verse. I hope Joshua will add my fix to the live 
code (fame at last:-).

The next question to ask is why, after the data was converted to a string, 
converting it back to a DateTime with DateTime.Parse reversed the month and 
day. To try to find that out, I executed the following code...

DateTime d = new DateTime(2006, 05, 11, 12, 0, 0);
String s = d.ToString();
        
Console.WriteLine("DateTime starts as {0:yyyy-MM-dd HH:mm:ss}", d);
Console.WriteLine("ToString gives {0}", s);
d = DateTime.Parse(s);
Console.WriteLine("DateTime ends up as {0:yyyy-MM-dd HH:mm:ss}", d);

The output from this was...

DateTime starts as 2006-05-11 12:00:00
ToString gives 11/05/2006 12:00:00
DateTime ends up as 2006-11-05 12:00:00

This indicates that DateTime.Parse will not reverse the action of 
DateTime.ToString, which I consider to be another bug. Running the same 
program on Windows using Microsoft.NET gives the correct answer.

By the way,  If I want to be friendly, what do I call you - Senganal, or T? 
And what does the "T" stand for?
