Troubleshooting time management
Your system might encounter problems with system time. This information provides solutions and recovery steps for some common system time problems.
- Offset from UTC was incorrectly set during i5/OS installation
If the offset from UTC (QUTCOFFSET) system value was not set correctly during the installation, the initial time zone value for your system might not be correct.- System time is incorrect and jobs are not running with the proper time
If your system time is incorrect and your jobs are not running with the proper time, your time settings might not have been specified correctly.- System time is off more than 2 hours
This situation can happen if your system time was incorrectly adjusted for observance of daylight saving time (DST), or if the time zone was set incorrectly during i5/OS® installation.- System time adjusted 2 hours for DST rather than 1 hour
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 one time adjustment might occur.- 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.- I cannot edit my time zone
If you cannot edit a time zone, typically, it is because you do not have the proper authority.- My time zone is not displaying the Standard Time and DST names correctly
The time zone uses a message file to specify the full or abbreviated names for either Standard Time or daylight saving time (DST). However, the time zone names are not displayed correctly when the system fails to retrieve the message.- I want to stop Simple Network Time Protocol
There are circumstances in which you might want to stop Simple Network Time Protocol (SNTP). Use this topic to find out how to do this in different situations.
