Description
The configuration option SYS/ddmmyy is set to d-m-y which has issues:
1. Date display can be ambiguous if a 2-digit year could also be a day in a month, e.g. 21-04-23 could be 2021-04-23 or 2023-04-21
2. Date display can be unclear for dates in a different century, e.g. 21-04-71 could be 2071-04-21 or 1971-04-21
3. The current format is kind-of-German where d.m.y or d.m.Y would be used. Given that TYPO3 targets an internal audience, a bias like this should be removed.
For these reasons the usual ISO date format Y-m-d should be used by default to solve these issues.
Also see https://en.wikipedia.org/wiki/List_of_date_formats_by_country where basically all countries prefer a 4-digit year to avoid the above mentioned ambiguities.
