incorrect radacct AcctSessionTime

[Gunther]

Just one observation ...

>From time to time I see entries in the radacct AcctSessionTime column with
over 1 billion seconds,
despite that the StopTime minus StartTime is less than 5 seconds.
With FR 1.0.5 it was a few times 2147483647: 

AcctStartTime		AcctStopTime		AcctSessionTime	inOctets
outOctets
2005-10-06 03:34:30 	2005-10-06 03:34:34 	2147483647		1069

Now with 1.1.0 it is around 1142280970:
2006-03-14 00:16:29  	2006-03-14 00:16:32  	1142280970		100

While the number of transferred octes is usually less than 200 bytes.
There are less than 15 users at the same time (GMT time) using the server.
There is some heavy download activity before ...

I presume that the NAS (wrt54g with Chillispot) is sending the incorrect
information ...
Is this correct?
