This means it may see a connection start, then immediately expire it as having passed the session time limit. [What? That session is six months old!] 

That’s actually not how Bro works, it uses the timestamps in the packets to drive it’s packet clock forward.  Could you show how you’re running Bro?  It sounds to me like you’re replaying traffic to and interface and then sniffing it.
