The Adjust Time (QWCADJTM) API will adjust the time by increasing or decreasing the time-of-day clock to a maximum change of plus or minus two hours.
|
|
</p>
|
|
|
|
<p><strong>Note:</strong> A time-of-day adjustment will remain active until completed unless one of the following occurs:</p>
|
|
|
|
<ul>
|
|
<li>A new time-of-day clock adjustment is started for the system.</li>
|
|
<li>The time-of-day clock for the system is changed.</li>
|
|
<li>The system is powered off.</li>
|
|
</ul>
|
|
|
|
<p>
|
|
The Retrieve System Time Information(QWCRTVTM) API can be used to determine if an adjustment to the time-of-day clock is allowed and can be used to retrieve information on any time adjustment that may be currently active.
