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:

Yep, the man page says that if you don't specify the time (and by time,
it means the hh:mm:ss part of the date-time) it chooses now.
-te, --end [end-date] [end-time]
Search for events with time stamps equal to or before
the given end time. The format of end time depends on your locale. If
the date is omitted,
today is assumed. *If the time is omitted, now is
assumed.* Use 24 hour clock time rather than AM or PM to specify
time. An example date is
10/24/2005. An example of time is 18:00:00.

OH! I wondered why the last event for yesterday seemed strangely close
to today's time. It didn't occur to me that today's time would matter on
a date in the past.
Thank you! I appreciate the clarification.

Looks like a problem. FYI, using aureport shows the exact time range selected
for the search. (Aureport and ausearch share the same time code.)

Seems like it is operating true to the man page (earlier email).
No?
I do not agree with the behavior...but agree it is consistent.
Here is my aureport data:
[root@audit audit]# date ; aureport -ts yesterday -te yesterday -i
Fri Jun 5 10:38:02 CDT 2009
Summary Report
======================
Range of time in logs: 06/04/2009 00:01:01.595 - 12/31/1969 18:00:00.000
Selected time for report: 06/04/2009 00:00:00 - 06/04/2009 10:38:02
...
But that also has possible issues (something might be wrong with the
range):
[root@audit audit]# ausearch -i -ts 12/31/1969 18:00:00.000 --just-one
Error - year is 1969

Well, I don't think assuming a time of now is the right thing to do for
keywords that mean something in the past. It should be midnight for an ending
time.
