The timezone property sets the time zone used for timestamps in the deliverable’s audit log. It must be a valid IANA Time Zone Database identifier (for example, America/New_York or Europe/London). If not specified, the account’s default time zone is used. Set your account default in the Settings section of the dashboard.
