Those are of course not the ones you need to look at since those have to do with the zone itself and not the zone records each of which has its own TTL. > I'm not aware of any universal way to get that at the application level, > using the system resolvers.

First of all because it doesn't support AAAA records and we require IPv6 support and second because of the GNU Licensing. My preference would be for ISC to provide a new api which will provide among other things the TTL information about the answers returned. It could be done as part of a DNSSEC resolver api effort which would also encourage implementation of DNSSEC.
