Time management

 

Within the time management component of iSeries™ Navigator, you can work with the time zone and time adjustment functions. With these functions, you can choose a time zone for your system to use and adjust the system time.

In addition, you can identify the software to use as the time maintenance application that synchronizes your system time with an external time source.

With the time zones function, you can specify a time zone for your system to use. Many time zone descriptions are provided with the system and you can also create your own. Time zone descriptions include whether your system should observe daylight saving time (DST). If your system observes DST, the system automatically updates the system time when DST starts and ends.

The time adjustment function allows you to adjust the system time by manually starting a time adjustment. In addition, you can identify a time maintenance application to use to adjust the system clock to keep it synchronized with an external time source.

In addition, you can work with time management using iSeries Navigator tasks on the Web. This allows you to work with time management functions using a Web browser.

    To begin taking advantage of the time management function, you need to set up your systems to use time management. For example, you need to set up your systems to use time zones and time adjustment applications.

  • Managing system time
    You can manage your system time in various ways. You can use a time maintenance application to make time adjustments, or you can manually specify a time adjustment.

  • Managing time zones
    The time zone (QTIMZON) system value specifies the name of the time zone description used to calculate the local system time. Depending on the time zone description in use, the i5/OS® operating system can automatically adjust the local system time to observe daylight saving time (DST).
