<div><p>Synchronize system times on your network.</p>
<div class="p"><p>Network authentication service uses 5 minutes (300 seconds) as
the default for the maximum amount of time that system times can be different.
You can change the clock difference by working with the network authentication
service properties. </p>
<p>Before synchronizing system times, use the QTIMZON
system value to set your system time according to your time zone. You can
synchronize these system times by changing the time that is set on the Kerberos
server or use the QTIME system value to change the iSeries™ system time. However, to keep
system times in a network synchronized, you should configure Simple Network
Time Protocol (SNTP). SNTP allows multiple systems to base their time on a
single time server.</p>
</div>
<div class="p"><span>To configure SNTP, complete the following:</span><ul><li>To configure <a href="../rzakt/rzaktkickoff.htm">SNTP</a> on an iSeries, enter <tt>CHGNTPA</tt> on a
command line.</li>
<li>To configure SNTP on Windows<sup>®</sup> systems, use <strong>NET HELP TIME</strong> to
display configuration information for a SNTP server.</li>
