Time adjustment is incorrect

If a time maintenance application is performing an incorrect time adjustment, or if you manually specified an incorrect time adjustment, you can stop the current time adjustment.

You need to stop the time adjustment if the time maintenance application is not making the proper time adjustments or if you specified the wrong time value for a time adjustment.

These recovery steps stop the current time adjustment that is incorrect, whether it was initiated by a time maintenance application or manually. These steps do not stop the time maintenance application from making additional time adjustments. You need to stop the time maintenance application to stop it from making additional adjustments to the system time. The procedure to stop an application is unique to each time maintenance application.

After the time adjustment stops, the system time is set to the current time value. The system does not go back and set the time value to the original setting before the adjustment began, nor does the system complete the adjustment. Therefore, you need to start a new time adjustment to set the system time back to its original value. The original value is the system time before the time adjustment began.

To stop the current time adjustment and specify a time adjustment that is correct, complete the following steps:

  1. From IBM® Navigator for i, expand Configuration and Service > Time Management.
  2. Right-click on Time Adjustment and click Open.
  3. View the amount of time in the Adjustment remaining field. You will need this value when you adjust the time to its original value.
  4. Click Stop adjustment.
  5. Click OK to continue the request.
  6. Click Start new time adjustment to start a new time adjustment.
  7. Specify an Amount of time that includes the amount of time that the system time adjusted incorrectly.
    To determine the amount of time needed to adjust the system time to its original value, subtract the adjustment remaining (from 3) from the original time adjustment. This is the amount of time to adjust to make up for the incorrect time adjustment. For an example, see Details.
  8. Click OK to start the new time adjustment.
Details: To determine the amount of time for the new time adjustment, consider this example. Before any time adjustments occurred, the system time was 2:30 p.m. Then, you started a time adjustment of -00:30:00 (30 minutes backward). Then, you realized that the time adjustment was supposed to be +00:30:00 (30 minutes forward). By this time, the system time had adjusted 5 minutes of the total 30 minutes. The adjustment remaining field specified 00:25:00 (25 minutes). Therefore, you need to start a new time adjustment that compensates for the 5 minutes that the time adjusted incorrectly. The new time adjustment needs to be +00:35:00 (35 minutes forward) where 5 minutes compensate for the incorrect adjustment that has already been completed and 30 minutes for the correct adjustment.
