970N/A signs a zone. It generates
970N/A NSEC and RRSIG records and produces a signed version of the
970N/A zone. The security status of delegations from the signed zone
970N/A (that is, whether the child zones are secure or not) is
970N/A determined by the presence or absence of a
970N/A <
code class="filename">keyset</
code> file for each child zone.

1265N/A Specify the date and time when the generated RRSIG records
1265N/A become valid. This can be either an absolute or relative
1265N/A time. An absolute start time is indicated by a number
1124N/A in YYYYMMDDHHMMSS notation; 20000530144500 denotes
98N/A 14:45:00 UTC on May 30th, 2000. A relative start time is
493N/A indicated by +N, which is N seconds from the current time.
98N/A If no <

1026N/A time is indicated in YYYYMMDDHHMMSS notation. A time relative
1124N/A to the start time is indicated with +N, which is N seconds from
1003N/A the start time. A time relative to the current time is
98N/A indicated with now+N. If no <

493N/A When a previously-signed zone is passed as input, records
493N/A may be resigned. The <
code class="option">interval</
code> option
493N/A specifies the cycle interval as an offset from the current
493N/A time (in seconds). If a RRSIG record expires after the
493N/A cycle interval, it is retained. Otherwise, it is considered
1026N/A to be expiring soon, and it will be replaced.
557N/A The default cycle interval is one quarter of the difference
1176N/A between the signature end and start times. So if neither
493N/A <
code class="option">end-time</
code> or <

1196N/A interval of 7.5 days. Therefore, if any existing RRSIG records
1196N/A are due to expire in less than 7.5 days, they would be

1357N/A and <

1357N/A This option is primarily intended to be used for dynamic

851N/A When signing a zone with a fixed signature lifetime, all
851N/A RRSIG records issued at the time of signing expires
98N/A simultaneously. If the zone is incrementally signed,
i.e. 1193N/A a previously-signed zone is passed as input to the signer,
1193N/A all expired signatures have to be regenerated at about the
1193N/A same time. The <
code class="option">jitter</
code> option specifies a
591N/A jitter window that will be used to randomize the signature
963N/A expire time, thus spreading incremental signature
910N/A Signature lifetime jitter also to some extent benefits
1097N/A validators and servers by spreading out cache expiration,
910N/A i.e. if large numbers of RRSIGs don't expire at the same time
98N/A from all caches there will be less congestion than if all
98N/A validators need to refetch at mostly the same time.
