Changing time zone settings

In some application environments, it is important that application server components use the same time zone. You can use the administrative console or system environment variables to ensure that your application components use the correct time zone.

Before you begin

Verify that extended National Language Support (NLS) is installed on your i5/OS® server. If extended NLS support is not already installed, install it by selecting option 21 when you install the base operating system (5769-SS1).

Determine the scope at which you want to set the time zone value. You can set the time zone value such that is applies for an entire cell, for an entire node, or only for a specific server.

Remember that time zone IDs should include an offset and, in almost all cases, a daylight saving time zone name for consistent results. For example, specify EST5EDT for Eastern Standard Time, Daylight Savings Time.

About this task

In general cases, the time zone for application server is inherited from the time zone that is set for the operating system; Java should be inherit the time zone from the operating system, and the application server will use the time zone that is set for each Java Virtual Machine (JVM). If you need to configure a different time zone for a single JVM, you can set the TZ environment variable in the application server, modify the properties file, or specify a command-line parameter when the JVM starts.

You can change the time zone setting for your application logs for all of the processes running in a single application server, for all of the application servers running under a user profile, or for all of the JVM processes running on the WebSphere® Application Server subsystem.

Procedure

Results

Your new time zone setting are in affect for the designated servers.
