Datetime string formatting and CultureInfo

I was suprised to see FxCop complaining that I wasn't specifying a CultureInfo in the following:

string s = day.ToString("ddd");

Surely the format string param in ToString is completely independent of CultureInfo? Is there any way which CultureInfo could affect the returned string?

EDIT: sorry, this is a total fail of a question. It's obvious that "ddd" should be dependent on culture settings. I was really thinking more of a case like DateTime.Now.ToString("dd-MM-yy"), but it looks like FxCop doesn't in fact complain in that instance.

DateTime.ParseExact(day.ToString(), "ddd", DateTimeFormatInfo.InvariantInfo)

DateTimeFormatInfo.InvariantInfo gives you default culture independent DateTimeFormatInfo.

There is an article on MSDN on How to extract the Day of the Week from a Specific Date. You will find many different examples on culture on that page, including this one:

DateTime dateValue = new DateTime(2008, 6, 11);
Console.WriteLine(dateValue.ToString("ddd"));    // Displays Wed

DateTime dateValue = new DateTime(2008, 6, 11);
Console.WriteLine(dateValue.ToString("ddd", 
                  new CultureInfo("fr-FR")));    // Displays mer.
