What can I do with this system value?

Use the time adjustment (QTIMADJ) system value to identify the software to use to adjust the system clock to keep it synchronized with an external time source. The system does not enforce the software specified; it only identifies the software to use. This value should be maintained by the time adjustment software and is intended as an aid to prevent having multiple time adjustment applications conflict with each other. There are no checks performed by the system to verify this value or that this software is or is not performing time adjustments.

Time adjustment software should check this system value prior to 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 this system value, the software should update this system value to identify that it is now responsible for adjusting the system clock. Time adjustment software should check this system value again prior to ending. This system value should be set to the value None (*NONE) only if the current value identifies this time adjustment software that is ending.

You can work with time adjustment system value in iSeries Navigator by expanding Configuration and Service > System Values > Date and Time > Configuration and Service. To work with the time adjustment function, expand Time Management > Time Adjustment.

Where can I get more information about this system value?
