About Time Zone
Time zones are configurable in the Configuration Console. Active time zones define the list of time zones for users to choose from when setting a future effective date for action requests in applications.
Initially, all time zones, except the default time zone, are set to inactive.
In the Configuration Console, you can activate a time zone, change the description, and change the default time zone for the data area. For example, if your corporate headquarters are in Chicago, you may want to change the default data area to America/Chicago and change the display name from "Central Standard Time" to "Chicago (Corporate)."
If an application form has been configured to include an Effective Time Zone field, users can choose from active time zones and the system will trigger the request to become effective at midnight in the selected time zone. If the user does not select a time zone, the system will use the default time zone for the data area. If there is no default time zone, the system will use the server time.
