Setting Up Your Environment to Support Global Time Zone

Global deployments typically span multiple time zones, making it difficult to manage time-sensitive information that must be exchanged among customers and employees working around the world. You can use the Global Time Zone feature to monitor the transfer of tasks between sites in different time zones.

The Global Time Zone feature converts and stores date and time data, using the Universal Time Coordinated (UTC) standard, which is equivalent to Greenwich Mean Time, but without daylight savings time.

You also need to make sure that time on all your machines are in sync by using a common NNTP server for time synchronization.

If you intend to operate your deployment with the Global Time Zone feature enabled, you must also set the operating system of your database servers to UTC time, or its equivalent. It is recommended that you change the time zone for the hosted application and not for the entire server. To change the operating system time, consult the vendor documentation for your operating system.

For more information on enabling Global Time Zone, see the Global Deployment Guide.

For restrictions on installing and configuring UTC on DB2 UDB for z/OS, see Implementing Siebel Business Applications on DB2 UDB for z/OS.

NOTE:  The Global Time Zone parameter (Universal Time Coordinated system preference) is enabled (set to TRUE) by default. If you do not want to enable the Global Time Zone feature, you must reset this system preference to FALSE by navigating to Administration - Application > System Preferences.
