This column, on the export reports page, shows when the system last retrieved cached usage data for a downloadable report.
The date and time does not reflect the actual usage data collection time; it simply shows the time when the report was generated using cached data. Every time you click Generate CSV Report, the time stamp in this column is updated. This column is cleared after every scheduled data update. If the report has not been generated since the last scheduled update, the column is blank.
The date is shown in the month/day/year format.
