Or the profile of ISO 8601 described in RFC3339.

If the use case is to publish the time at which a particular RRSet was last modified, then perhaps you also need to encode the class and the rrtype in there (and I guess if you're using TXT, you'd better not plan to publish the date on which some other TXT RRSet was changed).
