The accounting messages *must* have either an Event-Timestamp, or Acct-Delay-Time, or both. Otherwise, you have race conditions: 1) NAS reboots 2) user "bob" goes online 3) server receives accounting start for user "bob" 4) server receives accounting "on" for NAS. Having Event-Timestamp / Acct-Delay-Time in all packets means that (3) and (4) can be correctly ordered. Otherwise, in stage (3), the server marks "bob" online, and immediately after in stage (4), marks "bob" offline, because the NAS just rebooted.
