What's in the audit logs starting now. aureport uses the exact same code as 
ausearch for time operations, so its more informative to use it to see what 
time is actually resolved from these keywords. I get:

Summary Report
======================
Range of time in logs: 04/25/2008 09:31:10.388 - 05/02/2008 09:57:20.859
Selected time for report: 05/02/2008 00:00:00 - 05/02/2008 09:57:20.859

Which is clearly wrong. This looks like its resolving to today instead of now. 
I expect ausearch --start now to return nothing unless the system is busy 
doing a lot of logging and you get records between the time it gets system 
time until the time it opens the last log file for reading.

No, tail is not easy to do. Patches are welcome if anyone wants to do it. But 
you can do:

tail -f /var/log/audit/audit.log | ausearch -i

if you wanted that.
