You can override the user’s time zone selection with one that's consistent for all users.

1. Determine the time zone that's set for the server on which Presentation Services is running.
2. Use elements in the Presentation Services configuration file (instanceconfig.xml) or use session variables.
   The instanceconfig.xml file is located in: BI_DOMAIN/config/fmwconfig/biconfig/OBIPS
   Consult the following:

   • See What Is the Precedence Order for Time Zones? for information about the precedence order for time zones.

   • See Description of Time Zone Settings for descriptions of the session variables and elements.

   • See Example: Configuration File Settings for Specifying the Time Zone.

   • See Visualizing Data in Oracle Analytics Server for complete information about session variables.

3. Encourage end users to specify their preferred time zones using the My Account dialog.
4. Encourage users who create analyses to do the following to set the time stamps for their analyses:
   1. Use the Data Format tab of the Column Properties dialog to specify the time zone that's displayed in the columns of their analyses.
   2. Use the Time Zone dialog to set the time zone that's displayed in dashboard prompts.
