This option is only visible when a number of years is chosen in the Years Back field, rather than the default Lifetime selection. If an End Date is specified, it will be used to determine both the start and end date for the range of years as selected in the Years Back field. If an End Date is not specified, UNIWeb will use the date of your download request as the start date for the range of years as selected in the Years Back field, and will include all relevant information dated through the present and into the future in the downloaded document.
