Hi,
You have to distinguish about the "actual" value which is stored without any format and how it is shown or entered as a string which depends on country conventions (or using some more general format when shown to developers).
You have the same thing for decimal numbers ie you'll see 1.234 in your db or in your C# code even though some countries are using 1,234 (ie a comma rather than a point as the decimal separator) to show or input this value.
