Unix timestamp to Oracle timestamp conversion

Question

Hi all,
I am trying to convert the UNIX timestamp to ORACLE timestamp .
I have done like this upto now.
CREATE OR REPLCACE FUNCTION unixts_to_oraclets(unixtimestamp IN INTEGER)
RETURN DATE IS
result DATE;
BEGIN
result := TO_DATE('1970-01-01', 'YYYY-MM-DD') + numtodsinterval(unixtimestamp, 'SECOND');
return(result);
end unixts_to_oraclets;
now i have run this query
SQL> select unixts_to_oraclets(1139291114) as TS from dual;
TS
07-FEB-06
now i need the ouput to like this 07-FEB-06 01:10:12
for that i have done like this:
DECLARE
v_date DATE;
res_date DATE;
BEGIN
SELECT from_uts(1139291114)INTO v_date FROM dual;
SELECT TO_TIMESTAMP(v_date,'DD-MON-RRHH24.MI.SS.FF') INTO res_date FROM dual;
DBMS_OUTPUT.PUT_LINE(res_date);
END;
but the output is :
SQL> /
07-FEB-06
PL/SQL procedure successfully completed.
why is that it is not printing 07-FEB-06 01:10:12 ?
how should i moodify the code to get the desired output.
please help me i this regard
