<h1 class="topictitle1">Use the time adjustment function</h1>
<div><p>If you need to adjust the system time by two or fewer hours, use
the time adjustment function to change the system time.</p>
<div class="section"><p>A time adjustment is preferred over manually changing the time
of day system value because it incrementally speeds up or slows down the rate
at which time moves forward rather than making one single, instantaneous change
in time. A large jump in time, either forward or backward, can cause unpredictable
errors if jobs are concurrently accessing system time.</p>
<p>If your system
time is off more than 2 hours and you do not need to change the system time
immediately, you can use multiple time adjustments to reach the desired time
value. For example, if your system time is off 3 hours, you can make a 2-hour
time adjustment and a 1-hour adjustment to make a total adjustment of 3 hours.</p>
<p>To
make a time adjustment, complete the following steps:</p>
