Relevant versions: OS: Ubuntu 22.04 Koha: 23.11.04-4 MySQL: 8.0.36-0ubuntu0.22.04.1 When using Auth_with_ldap, new borrowers that are created via LDAP have an updated_on date of 0000-00-00 00:00:00. Guessing this may be related to comments in https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=18016 May also be a side effect of explicitly declaring a default_value of \"current_timestamp" for updated_on in Koha/Schema/Result/Borrower.pm. (Guessing no one else is still using LDAP to create accounts)
