    DNSSEC timing: absolute, relative and administrative timestamps

    22 February 2016 DNSSEC has changed the world of the DNS operator in two key respects. First, it has transformed the DNS from a primarily administrative system into a much more complex cryptographic platform (NL) that can be used for a wide variety of new applications (NL). Second, DNSSEC has introduced absolute times to a system that previously used only relative times (TTLs). Furthermore, with DNSSEC, the two timing methods need to interact. In this article, we consider the timing aspects of DNSSEC by reference to the settings in OpenDNSSEC (NL) (in the file /etc/opendnssec/kasp.xml).
