What can I do with this system value?

You can identify the software used to synchronize the system time with an external time source. The system value 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. The system does not perform checks to verify this value or to verify whether this software is performing time adjustments.

Time adjustment software should check this system value before starting. If this system value has an identifier for other time adjustment software, the software being started should notify the user of this potential conflict and confirm that it should be started. When no identifier is 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 before ending. This system value should be set to None (*NONE) only if the current value identifies this time adjustment software that is ending.

To work with the Time adjustment system value in IBM Navigator for i, select Configuration and Service > System Values. Right-click on Date and Time and click Properties, then switch to Time tab. To work with the time adjustment function, open Time Management, right-click on Time Adjustment and click Open.
