In that setup, where does one get AcctStartTime and AcctStopTime values?
- is it from the NAS?
- is it determined by the radius when writing to detail file, and
everything after that simply reads what's in the detail file?
- Or does every radius/SQL server involved create its own depending on
when it receives the packet/query?
