Looks like your dns_rr table is missing the default value of current_timestamp(). The modules does not sent a stamp value.
For those interrested in provisionning server and domain billing software. I've found https://www.boxbilling.org/ that change to opensource and they have an ispconfig pluggin https://github.com/boxbilling/extensions/blob/master/bb-library/Server/Manager/Ispconfig3.php Anybody had a chance to test it? ( or have comments on it ?)
