You can format the date to the pattern defined in the locale specific attribute datePattern. In case the locale specific attribute is not specified, the date format pattern is loaded from the default date pattern tag of the locale. If neither are defined, the default pattern from the code is used.
All supported locales are listed by default in the configuration file.
You have configured the date format.
Example
