Can we have time stamps on the csv data export

There is a CSV download for leave request, should also have date-time stamp column and each activity should be listed separately. for eg, when a leave is applied for, it should be timestamped, similarly when it is approved, it should be time stamped, when a leave is cancelled, it should be timestamped. This is a critical report which is used to process leaves in payroll. Normally a payroll user will process all activities within before the payroll cut-off. Those which occur after the cut-off is processed in the next pay-run. Without the time stamp, the payroll user cannot distinguish between leaves that were process in the previous pay-run from the current one.Can we have time stamps on the csv data export
