Bookshelf v10.1.3.2: Description of Time Zone Settings

Table 4 describes the session variables and the elements in the Oracle BI Presentation Services configuration file (instanceconfig.xml) with which you set time zones. When you include elements in the instanceconfig.xml file, then you specify the time zone that all users see. When you use session variables, you can specify a different time zone for each user. If you use session variables and you specify values for the appropriate elements in the instanceconfig.xml file, then the values of the session variables override the settings in the instanceconfig.xml file.

Table 4. Time Zone Settings
Element	Session Variable	Description	Value
<DefaultDataOffset>	DATA_TZ	The time zone offset of the original data. To allow the time zone to be converted so that users see the appropriate zone, you must set the value of this element or variable. If you do not set this, then no time zone conversion occurs because the value is "unknown". For example, suppose you want to convert to Eastern Standard Time (EST), which is Greenwich Mean Time (GMT) - 5. You must specify this value to enable the conversion to EST.	An offset that indicates a number of hours away from GMT time. For example: "GMT-05:00" or "-300", which means minus 5 hours.
<DefaultDataDisplay>	DATA_ DISPLAY_TZ	Specifies the time zone to use for displaying data. If you do not set this, the value is the User-Preferred Time Zone.	One of the time zones that are specified in the TimeZones.xml file. See Specifying Time Zone Values.
<DefaultUserPreferred>	TIMEZONE	Specifies the users' default preferred time zone before they select their own on the My Account screen in Answers. If you do not set this, the value is the local time zone from Oracle BI Presentation Services.	One of the time zones that are specified in the TimeZones.xml file. See Specifying Time Zone Values.
<Logging>	na	The time zone of the time stamps that appear in log files that are generated by Oracle BI Presentation Services. If you do not set this, the value is the local time zone from Oracle BI Presentation Services	One of the time zones that are specified in the TimeZones.xml file. See Specifying Time Zone Values.
<TimeZone>	na	The parent element for the elements that affect the preferred time zone. A child of the <ServerInstance> element.	na
