6033N/A verifies that the DNSSEC keys for a given zone or a set of zones
6033N/A have timing metadata set properly to ensure no future lapses in DNSSEC
6033N/A If <
code class="option">zone</
code> is specified, then keys found in
6033N/A the key repository matching that zone are scanned, and an ordered
6033N/A list is generated of the events scheduled for that key (
i.e.,
6033N/A publication, activation, inactivation, deletion). The list of
6033N/A events is walked in order of occurrence. Warnings are generated
6033N/A if any event is scheduled which could cause the zone to enter a
6033N/A state in which validation failures might occur: for example, if
6033N/A the number of published or active keys for a given algorithm drops
6033N/A to zero, or if a key is deleted from the zone too soon after a new
6033N/A key is rolled, and cached data signed by the prior key has not had
6033N/A time to expire from resolver caches.
6033N/A If <
code class="option">zone</
code> is not specified, then all keys in the
6033N/A key repository will be scanned, and all zones for which there are
6033N/A keys will be analyzed. (Note: This method of reporting is only
6033N/A accurate if all the zones that have keys in a given repository
6033N/A share the same TTL parameters.)

6033N/A The value of <

6033N/A Sets the value to be used as the maximum TTL for the zone or
6033N/A zones being analyzed when determining whether there is a
6033N/A possibility of validation failure. When a zone-signing key is
6033N/A deactivated, there must be enough time for the record in the
6033N/A zone with the longest TTL to have expired from resolver caches
6033N/A before that key can be purged from the DNSKEY RRset. If that
6033N/A condition does not apply, a warning will be generated.
6033N/A The length of the TTL can be set in seconds, or in larger units

6033N/A Sets the value to be used as the DNSKEY TTL for the zone or
6033N/A zones being analyzed when determining whether there is a
6033N/A possibility of validation failure. When a key is rolled (that
6033N/A is, replaced with a new key), there must be enough time
6033N/A for the old DNSKEY RRset to have expired from resolver caches
6033N/A before the new key is activated and begins generating
6033N/A signatures. If that condition does not apply, a warning

6033N/A Sets the value to be used as the resign interval for the zone
6033N/A or zones being analyzed when determining whether there is a
6033N/A possibility of validation failure. This value defaults to
6033N/A 22.5 days, which is also the default in
