<h1 class="topictitle1">Synchronize date and time values</h1>
<div><p>Management Central gives you a convenient way to synchronize date
and time values across your network.</p>
<p>To synchronize the date and time values across your network, select your
endpoint systems or system groups whose date and time values you want to update
from the <span class="uicontrol">Endpoint Systems </span>list under Management Central
in iSeries™ Navigator.
Then, right-click any selected system and select <span class="menucascade"><span class="uicontrol">System
Values</span> &gt; <span class="uicontrol">Synchronize Date and Time</span></span>.
Specify a model system that has the most accurate date and time values.</p>
<p>The date and time system values that are updated on the target systems
include system date (QDAYOFWEEK, QDATE, QDAY, QMONTH, QYEAR), time of day
(QTIME, QHOUR, QMINUTE, QSECOND), and time zone (QTIMZON). To verify that
a time adjustment is being made, select the endpoint system from the list
under My Connections (or your active environment) in iSeries Navigator. Then, go to <span class="menucascade"><span class="uicontrol">Configuration and Service</span> &gt; <span class="uicontrol">Time Management</span> &gt; <span class="uicontrol">Time Adjustment</span></span> to view the current time
adjustment.</p>
<p>The time used from the model system is the software clock time rather than
the QTIME system value. The software clock time is the same as the QTIME system
value except when the SNTP (Simple Network Time Protocol) client is started
on the model system. When SNTP is running on the model system, the software
clock is synchronized to the time server specified in the SNTP configuration.
For more information about configuring SNTP, see Simple Network
Time Protocol (SNTP).</p>
<p>You can choose to synchronize the time without changing the time zone,
or synchronize both the time and the time zone with those on the model system.</p>
<p>When a system changes to or from Daylight Saving Time (DST), the GMT offset
(QUTCOFFSET) system value is automatically updated from the GMT offset attribute
of the time zone (QTIMZON) system value.</p>
