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. Siebel Systems' Global Time Zone feature helps your organization meet contractual response times and commitments in spite of time zone differences.

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

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

Although enabling this feature is optional in Siebel 7, it is strongly recommended that you operate your production environment with Global Time Zone enabled.

NOTE:  The Global Time Zone parameter (Universal Time Coordinated system preference) is enabled (set to TRUE) in Siebel 7 by default. If you do not want to enable Global Time Zone feature, you must reset this parameter to FALSE through Server Manager by navigating to Application Administration >System Preferences.
