When you import a date to a field using this storage type, the date in the source file may contain special characters such as forward slashes (/). The Import Utility will add the date to a date field regardless of whether the special characters appear in the source file; however, the imported date will appear in the application you are using with the date format that you've set in your operating system's control panel settings.
As displayed in windows. All formatting is determined by the operating system settings.
