issue 94543, some progress and request for help

Greetings,

I have just added a patch and some test data and results to issue
94543 <http://www.openoffice.org/issues/show_bug.cgi?id=94543>. Points
arising ...

(*) I am not satisfied with my analysis of the impact of the change.
    For me to make any progress on this, I think I shall have to start
    over with {OpenGrok, considering the confusion I got into in my
    first attempt at analysis.  Perhaps someone here "just knows" that
    the change looks right or wrong?  Of course, having found the bug
    at two places, I have to fear that there is a third place which I
    have not found.

(*) "Contributing Patches"
    <http://wiki.services.openoffice.org/wiki/Contributing_Patches>
    assumes a working copy from cvs.  I lack that, so submitted a diff
    of from the files that I have.  Is this of any use?

(*) Along the way, a couple of things in the cod have raised my
    eyebrows a little bit.  Are they candidates for fixes?

      - The last case the switch structure ending at
        connectivity/source/drivers/odbcbase/OTools.cxx line 394 lacks
        a break statement.

      - Line 248 of the same file assigns a literal constant to
        _nColumnSize.  I think it would be better to use
        SQL_TIMESTAMP_LEN defined at unixODBC/inc/sql.h line 55.
