|
<div><p>View this topic to learn some basic techniques to properly set
|
||
|
|
up a typical time maintenance application. </p>
|
||
|
|
<p>Each time maintenance application is unique to your business environment.
|
||
|
|
You can use the IBM-supplied Simple Network Time Protocol (SNTP) application
|
||
|
|
or an application of your own to use for time maintenance.</p>
|
||
|
|
<p>When writing a time maintenance application, you should ensure that the
|
||
|
|
software checks the time adjustment (QTIMADJ) system value before starting.
|
||
|
|
If this system value has an identifier for other time adjustment software,
|
||
|
|
then the software being started should notify the user of this potential conflict
|
||
|
|
and confirm that this time adjustment software should be started. When there
|
||
|
|
is not an identifier associated with the time adjustment (QTIMADJ) system
|
||
|
|
value, the software should update the system value to identify that it is
|
||
|
|
now responsible for adjusting the system clock. Time adjustment software should
|
||
|
|
check this system value again before ending. The time adjustment (QTIMADJ)
|
||
|
|
system value should be set to the value None (*NONE) only if the current value
|
||
|
|
identifies this time adjustment software that is ending.</p>
|
||
|
|
<p>You can use the IBM-supplied SNTP application as a time maintenance application.
|
||
|
|
The SNTP application can act as a client or a server.</p>
