Yes, with the date format everything is more complicated - even more complicated than Sid Holland has mentioned. The reason is in some localization problems. For example, if your Windows system has Russian localization, you should use Russian letters in the date formats, like "ДД.MM.ГГГГ" or "ГГГГ-MM-ДД", and, therefore, you should be able to extract and apply these letters.
