<div><div class="section"><p><strong>Problem</strong></p>
|
||
|
|
<p>If the current time zone (QTIMZON) system
|
||
|
|
value observes daylight saving time (DST), the system automatically updates
|
||
|
|
the system time for DST. If the system is also set to use other automatic
|
||
|
|
adjustments for DST, more than 1 time adjustment might occur.</p>
|
||
|
|
<p>For example,
|
||
|
|
if your time zone (QTIMZON) system value is set to Eastern Standard Time (EST),
|
||
|
|
your system time will adjust 1 hour forward the first Sunday in April to observe
|
||
|
|
Eastern Daylight Time (EDT). In addition, you can have the i5/OS™ job scheduler
|
||
|
|
of iSeries™ Navigator
|
||
|
|
set to automatically adjust the system time 1 hour forward on the first Sunday
|
||
|
|
of April. With this environment, the system time adjusts a total of 2 hours
|
||
|
|
forward on the first Sunday of April rather than 1 hour.</p>
|
||
|
|
<p><strong>Recovery
|
||
|
|
steps</strong></p>
|
||
|
|
<p>If your system time was adjusted by other automatic methods
|
||
|
|
(such as the i5/OS job
|
||
|
|
scheduler), you need to disable the automatic adjustments and adjust the system
|
||
|
|
time 1 hour to compensate for the additional hour. To do this, complete the
|
||
|
|
following steps:</p>
|
||
|
|
</div>
|
||
|
|
<ol><li class="stepexpand"><span>Disable any other automatic time adjustments, if the time zone
|
||
|

that you are using observes DST.</span> <div class="note"><span class="notetitle">Note:</span> The steps to disable automatic

||
|
|
<li class="stepexpand"><span>Adjust the system time by 1 hour by completing the following steps:</span><ol type="a"><li><span>In iSeries Navigator,
