2.4.1 Time zones

When you use JP1/AJS3 - View to log in to JP1/AJS3 - Manager, and you check the jobnet execution statuses and execution results, the time displayed obeys the time zone set in the OS of the computer where JP1/AJS3 - View is installed.

In Windows:

When running JP1/AJS3 - Manager in Windows, you cannot set time zones for individual processes (a manager host cannot handle more than one time zone). If your system operates across time zones, set up manager hosts and JP1/AJS3 - View hosts separately for each time zone.

In UNIX:

UNIX allows you to set time zones in process units, so you can set a TZ environment setting variable for each registered user to execute jobnets registered for execution at JP1/AJS3 - Manager (you can use multiple time zones at a single manager host).

However, the following restrictions apply to operations on units:

• When working from JP1/AJS3 - View, since you can only handle one time zone, prepare unit definitions for each time zone and start JP1/AJS3 - View separately for each of these time zones.
• When you register jobs for execution, use the ajsentry command in an environment where a TZ environment variable is set for each time zone.
• Only relative specifications can be made for times (e.g. time changes).
• If you want to use a command to check the jobs registered for execution, use the ajsshow command in the environment with the same TZ environment variable that was used when the jobs were registered for execution.

When JP1/AJS3 - View is set up to display Japanese time for execution statuses and execution results, even if the jobnet is actually executed in another country, the time displayed will be Japan time, not the local time in that country. In Windows, to check jobnet execution statuses and execution results from a region with a different time zone in the local time, you have to prepare a computer set to the local time and running JP1/AJS3 - View. For example, to display the execution statuses from New York in New York time, prepare a JP1/AJS3 - View computer with its clock set to New York time. In UNIX, you can check execution results from areas with different time zones on a single JP1/AJS3 computer by setting a different time zone for each process.

The following figure shows a system configuration that allows you to check execution statuses on multiple hosts for administrative tasks in different time zones.

Figure 2-33 Example of a system configuration for checking jobnet execution status on manager hosts in different time zones

The table below provides cautionary notes when manager hosts and agent hosts operate in different time zones.

These cautionary notes apply when a scheduled job is executed, not when defining a jobnet execution schedule.

Jobnets are scheduled for execution based on the manager's time zone setting.

Table 2-15 Notes on time zones in a manager/agent configuration

Cautionary notes	PC job Unix job QUEUE job Custom job	Action job	Event job
Jobs are executed based on the agent's time zone setting. Times logged in the standard output file and standard error output file are based on the agent's time zone setting.	Yes	Yes	Yes
Times such as time-out periods defined in jobs are calculated based on the time zone setting of the agent, not the manager.	--	Yes	--
Times in information inherited from event jobs are based on the time zone setting of the agent where the event occurred, not the time based on the time zone setting of the manager or the time zone setting of the host that executes the job that uses the inherited information.	Yes	Yes	Yes
