F10, audit-1.7.12

[root@slim ~]# ausearch -i -ts yesterday -te yesterday | grep "node=" |
tail
...

node=slim type=PATH msg=audit(06/03/2009 19:11:29.348:2884) : item=0

The results end with the above record.

Then:
[root@slim ~]# ausearch -i -ts yesterday | grep "node=" | less

This shows plenty of events after the 19:11 event shown.
Any ideas?

Reading the manpage is a little confusing on the -ts and -te meanings.
I'm not sure I agree with the way it is stated, regardless the behavior
above appears wrong ... but this appears to work correctly:

ausearch -ts 06/03/2009 00:00:00 -te 06/03/2009 23:59:59 -i | grep
"node=" | tail
...
