|
|
<div><div class="section"><p><strong>Problem</strong></p>
|
||
|
|
<p>If the system time is off more than 2 hours,
|
||
|
|
one or more of the following conditions might exist:</p>
|
||
|
|
<ul><li>The time zone automatically adjusted the system time one hour for DST
|
||
|
|
and the system time was adjusted manually one hour for DST. Therefore, the
|
||
|
|
system time adjusted a total of 2 hours for DST rather than one hour.</li>
|
||
|
|
<li>The time zone was set incorrectly during the installation of i5/OS™ due to
|
||
|
|
any of the following conditions: <ul><li>The offset used to determine the time zone was wrong.</li>
|
||
|
|
<li>The wrong time zone was selected.</li>
|
||
|
|
<li>The offset specified in the time zone description was incorrect.</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<p>If you attempt to make a time adjustment for more than 2 hours, you
|
||
|
|
will receive an error message stating that you cannot make an adjustment that
|
||
|
|
is greater than 2 hours.</p>
|
||
|
|
<p><strong>Recovery steps</strong></p>
|
||
|
|
<p>To recover from
|
||
|
|
this situation, you can perform one of two different methods. You can manually
|
||
|
|
change the time of day system value or you can use multiple time adjustments
|
||
|
|
until the desired time value is reached. The method you use to change the
|
||
|
|
time of day depends on how quickly the system time needs to be fixed.</p>
|
||
|
|
<p>If
|
||
|
|
you need to change the system time immediately, you must manually change the
|
||
|
|
time of day system value. If you do not need to change the system time immediately,
|
||
|
|
you can use multiple time adjustments to gradually reach the desired time
|
||
|
|
value. The adjustment method requires multiple time adjustments because the
|
||
|
|
maximum time adjustment allowed is 2 hours and your system time is off more
|
||
|
|
than 2 hours. For more information about the implications of manually changing
|
||
|
|
the system time versus using a time adjustment, see Time adjustment.</p>
|
||
|
|
<p>Before
|
||
|
|
changing the system time using either method, complete the following steps:</p>

||
|
|

|

</ol>

<div class="section"><p>After you determine which method to use to change your system time,
|
||
|
|
see Update system time for step-by-step instructions on how to either manually
|
||
|
|
change the system time or how to use the time adjustment function.</p>
