In some application environments, it is important that application server components use the same time zone. You can use the administrative console to ensure that your application components use the correct time zone.
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.
When the East African Time Zone (EAT)
is specified as your time zone setting, the HP-UX operating system Java virtual machine (JVM) uses Greenwich Mean
Time (GMT). Therefore, log file time stamps are based on GMT instead
of EAT. The situation might also causes problems in server federation
if you attempt to synchronize with servers that are running on an
operating system whose JVM correctly handles the EAT.
If you need to use East African Time Zone as the
time zone setting for a specific function, instead of using the following
procedure, add the -Duser.timezone=EAT parameter to the appropriate
Java command. For example, to have an application server use EAT as
its time zone setting, add the -Duser.timezone=EAT parameter to the
startServer command.
You can specify the Unix System Services
(USS) TZ variable as a WebSphere® variable to set
the time stamps for your application logs.
You can change the time zone setting for 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.
You can use the WebSphere
TZ variable to change the time zone setting for a single application
server.
Complete one or more of the following actions to set appropriate time zone values for your environment.
