In SQL*Plus, you can get the client date to appear in a report title with the _DATE variable, but you cannot use it in a SELECT statement.

SQL> alter session set nls_date_format = 'DD-MON-YYYY HH24:MI:SS';

Session altered.

SQL> ttitle center _date
SQL> select sysdate from dual
  2  /

                              03-JAN-2007 16:58:47
03-JAN-2007 17:00:15


You can be a bit tricky and write the date to a file, then read it back in as a variable:

SQL> alter session set nls_date_format = 'YYYYMMDDHH24MISS';

Session altered.

SQL> ttitle left "define client_date=" _date
SQL> set heading off
SQL> spool cdate.sql
SQL> select NULL 
  2  from dual
  3  /

define client_date=20070103170748

SQL> spool off
SQL> @cdate
SP2-0734: unknown command beginning "SQL> selec..." - rest of line ignored.
SP2-0734: unknown command beginning "SQL> spool..." - rest of line ignored.
SQL> alter session set nls_date_format = 'DD-MON-YYYY HH24:MI:SS';

Session altered.

SQL> set heading on
SQL> ttitle off
SQL> select to_date(&client_date, 'YYYYMMDDHH24MISS') as client_date
  2  , sysdate as server_date
  3  from dual;
old   1: select to_date(&client_date, 'YYYYMMDDHH24MISS') as client_date
new   1: select to_date(20070103170748, 'YYYYMMDDHH24MISS') as client_date

If you are using some other client program (other than SQL*Plus) then you have to use some feature of that program. Since SQL and PL/SQL run on the server, it is IMPOSSIBLE for those languages to retrieve the client date; it MUST be done by the client tool/language.
