[Koha] UNIMARC_sync_date_created_with_marc_biblio.pl

Hi, I've noticed a problem with my biblio records. Biblio.datecreated and biblio.timestamp are well fullfilled in the database but are not displayed in the biblio record. I've executed this but with no results (in koha <https://github.com/colinsc/koha>/ misc <https://github.com/colinsc/koha/tree/master/misc>/ maintenance <https://github.com/colinsc/koha/tree/master/misc/maintenance>/) perl *UNIMARC_sync_date_created_with_marc_biblio.pl. Has someone an idea? Best regards, Samuel *
