I18n Issues

1. Could be the wrong locale (hard coded English)
2. Creating an "old-style" date formatter
3. NSDateFormatter attempts natural-language processing only after it fails to interpret an entered string according to format. Natural-language processing supports only a limited set of colloquial phrases, primarily in English. It may give unexpected results, and its use is strongly discouraged.

Resolution: You cannot use this method to initialize a formatter with the OS X v10.4 formatting behavior, you must use init. Initialize the formatter with init. If necessary, you can set the default class behavior using setDefaultFormatterBehavior:, or using setFormatterBehavior:message with the argument NSDateFormatterBehavior10_4.

Generally one needs to pass in locale, encoding or language to ensure that any culture-dependent conversion is done properly. If you determine that the call is i18n-safe, you can use Globalyzer's Ignore Comment functionality to ensure that it isn't picked up in a subsequent scan.
