ceiling() gives wrong answer for datetime

From working_tpch1/qa_fe_cnxFunctions/bug_3334_ceil.sql
select 'ceil(dtm)', id as id, dtm, ceiling(dtm) from dtypes;
I Should be:
ceil(dtm) id dtm ceiling(dtm)
-ceil(dtm) 1 2010-11-08 08:19:22 20101108081922
-ceil(dtm) 2 2010-11-01 08:18:22 20101101081822
-ceil(dtm) 3 2010-10-25 08:17:22 20101025081722
-ceil(dtm) 4 2010-10-18 08:16:22 20101018081622
-ceil(dtm) 5 2010-10-11 08:15:22 20101011081522
11:14
But in 1.5.4, we have
11:14
+ceil(dtm) 1 2010-11-08 08:19:22 0000-01-09 08:09:54
