eb0cc229f19c437a6b538d3ac0d0443268290b7eedp<p><span><strong class="command">dnssec-settime</strong></span>
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp reads a DNSSEC private key file and sets the key timing metadata
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp as specified by the <code class="option">-P</code>, <code class="option">-A</code>,
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp <code class="option">-R</code>, <code class="option">-I</code>, and <code class="option">-D</code>
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp options. The metadata can then be used by
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp <span><strong class="command">dnssec-signzone</strong></span> or other signing software to
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp determine when a key is to be published, whether it should be
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp used for signing a zone, etc.
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp </p>
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp<p>
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp If none of these options is set on the command line,
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp then <span><strong class="command">dnssec-settime</strong></span> simply prints the key timing
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp metadata already stored in the key.

eb0cc229f19c437a6b538d3ac0d0443268290b7eedp When key metadata fields are changed, both files of a key
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp pair (<code class="filename">Knnnn.+aaa+iiiii.key</code> and
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp <code class="filename">Knnnn.+aaa+iiiii.private</code>) are regenerated.
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp Metadata fields are stored in the private file. A human-readable
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp description of the metadata is also placed in comments in the key
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp file. The private file's permissions are always set to be
eb0cc229f19c437a6b538d3ac0d0443268290b7eedp inaccessible to anyone other than the owner (mode 0600).

<a name="id2543669"></a><h2>TIMING OPTIONS</h2>
<p>
Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS.
If the argument begins with a '+' or '-', it is interpreted as
an offset from the present time. For convenience, if such an offset
is followed by one of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi',
then the offset is computed in years (defined as 365 24-hour days,
ignoring leap years), months (defined as 30 24-hour days), weeks,
days, hours, or minutes, respectively. Without a suffix, the offset
is computed in seconds. To unset a date, use 'none' or 'never'.
</p>
<div class="variablelist"><dl>
<dt><span class="term">-P <em class="replaceable"><code>date/offset</code></em></span></dt>
<dd><p>
Sets the date on which a key is to be published to the zone.
After that date, the key will be included in the zone but will
not be used to sign it.
</p></dd>
<dt><span class="term">-A <em class="replaceable"><code>date/offset</code></em></span></dt>
<dd><p>
Sets the date on which the key is to be activated. After that
date, the key will be included in the zone and used to sign
it.
</p></dd>
<dt><span class="term">-R <em class="replaceable"><code>date/offset</code></em></span></dt>
<dd><p>
Sets the date on which the key is to be revoked. After that
date, the key will be flagged as revoked. It will be included
in the zone and will be used to sign it.
</p></dd>
<dt><span class="term">-I <em class="replaceable"><code>date/offset</code></em></span></dt>
<dd><p>
Sets the date on which the key is to be retired. After that
date, the key will still be included in the zone, but it
will not be used to sign it.
</p></dd>
<dt><span class="term">-D <em class="replaceable"><code>date/offset</code></em></span></dt>
<dd><p>
Sets the date on which the key is to be deleted. After that
date, the key will no longer be included in the zone. (It
may remain in the key repository, however.)
</p></dd>
<dt><span class="term">-S <em class="replaceable"><code>predecessor key</code></em></span></dt>
<dd><p>
Select a key for which the key being modified will be an
explicit successor. The name, algorithm, size, and type of the
predecessor key must exactly match those of the key being
modified. The activation date of the successor key will be set
to the inactivation date of the predecessor. The publication
date will be set to the activation date minus the prepublication
interval, which defaults to 30 days.
</p></dd>
<dt><span class="term">-i <em class="replaceable"><code>interval</code></em></span></dt>
<dd>
<p>
Sets the prepublication interval for a key. If set, then
the publication and activation dates must be separated by at least
this much time. If the activation date is specified but the
publication date isn't, then the publication date will default
to this much time before the activation date; conversely, if
the publication date is specified but activation date isn't,
then activation will be set to this much time after publication.
</p>
<p>
If the key is being set to be an explicit successor to another
key, then the default prepublication interval is 30 days;
otherwise it is zero.
</p>
<p>
As with date offsets, if the argument is followed by one of
the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi', then the
interval is measured in years, months, weeks, days, hours,
or minutes, respectively. Without a suffix, the interval is
measured in seconds.
