djs=# SELECT version();
                          version
-----------------------------------------------------------
 PostgreSQL 7.1 on i686-pc-linux-gnu, compiled by GCC 2.96
(1 row)

 INSERT INTO "ObjectLog1" VALUES (1, '2001-05-02 13:48:59.999', 0, 10, 1, 1,
 9, 0, 0, 0, 0);

 djs=# select "Date" from "ObjectLog1";
            Date
 ---------------------------
  2001-05-02 13:48:60.00+03
 (1 row)

 ------------------->13:48:60.00 !!!!!!
 It supposed to be 13:49:00.00

 Also this bug leads to invalid result of backup-restore procedure.
 Restore reports "Bad timestamp format"
 Also this bug enforces ODBC error message.

 djs=# select date_trunc('second', "Date"), date_part('milliseconds',
"Date")
 from "ObjectLog1";
        date_trunc       |    date_part
 ------------------------+------------------
  2001-05-02 13:48:59+03 | 999.000000000002
