Packet-Original-Timestamp

[Бен Томпсон]

Hello Everyone

I have a NAS which is not sending Event-Timestamp in accounting
messages. I wondered if I could create it in unlang by subtracting
Acct-Delay-Time from Packet-Original-Timestamp. However, when I put a
reference to Packet-Original-Timestamp in the acconting setion I get
the following error :-

Reference "${Packet-Original-Timestamp}" not found

Am I doing something wrong?
