Even if you want to change the culture setting, you can still run in formatting problems. If the user changes the settings of the culture in windows you still do not know what formatting rules (formatter) you can expect. For example changing the culture before parsing a datetime is a bad practice. If you need to parse a specific formatting, you can better make a formatter like:

dateString = "Sun 15 Jun 2008 8:30 AM -06:00";
format = "ddd dd MMM yyyy h:mm tt zzz";
try {
    result = DateTime.ParseExact(dateString, format, provider);
    Console.WriteLine("{0} converts to {1}.", dateString, result.ToString());
}
catch (FormatException) {
    Console.WriteLine("{0} is not in the correct format.", dateString);
}

Good practice is to assume that the users computer has the right formatting for the specific user. Then the user can give the values in the same format as any other program he uses.
