No. But it should be really close to:

(LogOffTime-AcctDelayTime)-(LogonTime=AcctDelayTime)

AcctSessionTime is authorative from the NAS and is not timestamp
calculated.

Thats really not a big deal. RADIUS accounting packets can
backup and if you are storing to an Access database, the
time for the record to get from RRAS, to RadiusNT to Acceess
(Access being the slowest) could easily be a second or two.
