    <para><command>dnssec-signzone</command>
      signs a zone.  It generates
      NSEC and RRSIG records and produces a signed version of the
      zone. The security status of delegations from the signed zone
      (that is, whether the child zones are secure or not) is
      determined by the presence or absence of a
      <filename>keyset</filename> file for each child zone.

            may be resigned.  The <option>interval</option> option
            specifies the cycle interval as an offset from the current
            time (in seconds).  If a RRSIG record expires after the
            cycle interval, it is retained.  Otherwise, it is considered
            to be expiring soon, and it will be replaced.

          <para>
            The default cycle interval is one quarter of the difference
            between the signature end and start times.  So if neither
            <option>end-time</option> or <option>start-time</option>
            are specified, <command>dnssec-signzone</command>
            generates
            signatures that are valid for 30 days, with a cycle
            interval of 7.5 days.  Therefore, if any existing RRSIG records
            are due to expire in less than 7.5 days, they would be
            replaced.

	    This option is primarily intended to be used for dynamic

            When signing a zone with a fixed signature lifetime, all
            RRSIG records issued at the time of signing expires
            simultaneously.  If the zone is incrementally signed, i.e.
309 310
            a previously-signed zone is passed as input to the signer,
            all expired signatures have to be regenerated at about the

            same time.  The <option>jitter</option> option specifies a
            jitter window that will be used to randomize the signature
            expire time, thus spreading incremental signature
            regeneration over time.
          </para>
          <para>
            Signature lifetime jitter also to some extent benefits
            validators and servers by spreading out cache expiration,
            i.e. if large numbers of RRSIGs don't expire at the same time
            from all caches there will be less congestion than if all
            validators need to refetch at mostly the same time.
