<h3 id="rzahqtimesync">Time synchronization</h3>
<p>To keep the time on i5/OS&trade; and the Windows environment synchronized, do the
following steps:</p>
<ol type="1">
<li>Select *YES for synchronize date and time in the Install Windows server
(INSWNTSVR) command or the CHGNWSD command. Selecting *YES will synchronize
the time between i5/OS and the integrated Windows server every 30 minutes.
Selecting *NO will synchronize the time only when the server is started.</li>
<li>Ensure that the iSeries&trade; time, date, and time zone are correct. Once these
values are set they will automatically update themselves every six months
for daylight savings time adjustments. The QTIMZON system value replaces the
need to manually change the QUTCOFFSET system value twice a year.</li>
<li>At the Windows console, click <span class="bold">Control Panel &mdash;>
Date/Time</span>, select the <span class="bold">Time Zone</span> tab and select
your time zone from the drop-down list.</li>
<li>Select the <span class="bold">Automatically adjust clock for daylight savings
changes</span> check-box. Then click OK.</li></ol>
<p>If you have problems with time synchronization, check the i5/OS system value
for LOCALE to make sure it is set properly.</p>

<div class="notebody">Time synchronization should be set to *NO for Windows
active domain servers and domain member servers. Since Windows Active Directory
has its own time synchronization facility, setting time synchronization to
*YES will cause a conflict.</div><img src="deltaend.gif" alt="End of change" />
