<div class="section"><h4 class="sectiontitle">What can I do with this system value?</h4><p>You can specify
|
|
the time that is used on your system. The time specifies the hour (QHOUR),
|
|
minutes (QMINUTE), and seconds (QSECOND).</p>
|
|
<p> When you need to update the
|
|
system time, a time adjustment is the preferred method. A time adjustment
|
|
ensures that time is not skipped or repeated. You can specify up to a 2 hour
|
|
time adjustment. If you need to update the system time more than 2 hours,
|
|
you can use multiple time adjustments to reach the desired time value. Only
|
|
make manual changes to the time of day system value if you need to change
|
|
the time immediately.</p>
|
|
<p>If the system observes Daylight Saving Time, you
|
|
cannot change the date and time to the hour that Daylight Saving Time affects.
|
|
For example, if the system clock moves from 2:00 to 3:00 on April 6 for Daylight
|
|
Saving Time, you cannot change the time to a value that is greater than or
|
|
equal to 2:00 and less than 3:00 on April 6.</p>
|
|
<p>In the iSeries Navigator
|
|
interface, the system date (QDATE) and time of day (QTIME) system values have
|
|
not changed. However, they are combined into one system value in the character-based
|
|
interface, QDATETIME. If you are accessing the date or time system value using
|
|
the character-based interface, use QDATETIME rather than QDATE or QTIME. In
|
|
the character-based interface, QDATE and QTIME are still accessible so you
|
|
can access the date and time values separately, if needed. Use the QDATE and
|
|
QTIME system values to retrieve values, and use the QDATETIME system value
|
|
to set the date, time, or both. This ensures that the system values do not
|
|
conflict with each other.</p>
|

|
|
<div class="section"><h4 class="sectiontitle">Where can I get more information about this system value?</h4><p>To
|
|
learn more, go to the date and time system values overview topic. If you are
|
|
looking for a specific system value or category of system values, try using
|
|
the i5/OS system
|
|
value finder.</p>
