System time adjusted 2 hours for DST rather than 1 hour

Problem

If the current time zone (QTIMZON) system value observes daylight saving time (DST), the system automatically updates the system time for DST. If the system is also set to use other automatic adjustments for DST, more than 1 time adjustment might occur.

For example, if your time zone (QTIMZON) system value is set to Eastern Standard Time (EST), your system time will adjust 1 hour forward the first Sunday in April to observe Eastern Daylight Time (EDT). In addition, you can have the i5/OS™ job scheduler of iSeries™ Navigator set to automatically adjust the system time 1 hour forward on the first Sunday of April. With this environment, the system time adjusts a total of 2 hours forward on the first Sunday of April rather than 1 hour.

Recovery steps

If your system time was adjusted by other automatic methods (such as the i5/OS job scheduler), you need to disable the automatic adjustments and adjust the system time 1 hour to compensate for the additional hour. To do this, complete the following steps:

Disable any other automatic time adjustments, if the time zone that you are using observes DST.
Note: The steps to disable automatic adjustments are unique to the application in use.
Adjust the system time by 1 hour by completing the following steps:
1. In iSeries Navigator, expand My Connections > server-name > Configuration and Service > Time Management > Time Adjustment.
2. Click Start New Time Adjustment. If a time adjustment is in progress, the current time adjustment will be stopped. Before proceeding, ensure that you should stop the current adjustment.
3. Specify one hour positive or negative, depending on whether you are starting or ending DST.
4. Click OK to start the time adjustment.
5. If a time adjustment is already in progress, click OK to stop the current adjustment and to begin the new adjustment.
