This option tries to convert every integer it finds in the meta values into a date in the format you specify.
Which value appears in your case?

Value I get is Ymd which is the default format ACF uses for storing dates in the database (eg. 19870921).
Value I would like to get is d-m-Y (eg. 21-09-1987).
No, this is not a timestamp. A timestamp is something like this: 1647675979
This is the number of seconds that have elapsed since the Unix epoch, excluding leap seconds. The Unix epoch is 00:00:00 UTC on 1 January 1970.
This is a bad-formed date. This is a bad practice from ACF, they could use the standard MySQL date format Y-m-d or a timestamp but they use this one that does not benefit anything in terms of performance but is completely out of standard.
Maybe in a future we will add some custom addon for ACF that will be able manage this kind of “mistakes” but now we cannot do it.
Anyway you can easily manage this data with Microsoft Excel or LibreOffice Calc.
