Validations on date components display in US date format: "mm/dd/yyyy". For example, if the system language is set to English (United Kingdom) / en_GB, and an invalid date is passed, the built-in validation is triggered and the following error message is displayed:
The value XX/XX/XXXX is not a valid date. Valid format is mm/dd/yyyy.
The expected en_GB date format should be: "dd/mm/yyyy". This is currently the behavior for all languages.
This issue has been addressed via AN-84725.
