How to insert date with timestamp into table values

Question

hi,
I have a table
create table abc1(dob date);
insert into abc1 values (to_date(sysdate,'RRRR/MM/DD HH24:MI:SS'))
but when i see in data base it shows as normal date without time stamp.
Is it possible to insert into back end with timestamp.
Thanks..

First, SYSDATE is a DATE already, no need to convert it to a DATE using the TO_DATE() function.
The date ALWAYS has a time component, whether or not it is displayed is up to your NLS settings. for example:
SQL> CREATE TABLE ABC1(DOB DATE);
Table created.
SQL> ALTER SESSION SET NLS_DATE_FORMAT='MM/DD/YYYY';
Session altered.
SQL> INSERT INTO ABC1 VALUES(SYSDATE);
1 row created.
SQL> SELECT * FROM ABC1;
DOB
02/04/2010
SQL> ALTER SESSION SET NLS_DATE_FORMAT='MM/DD/YYYY HH24:MI:SS';
Session altered.
SQL> SELECT * FROM ABC1;
DOB
02/04/2010 12:54:57
SQL> DROP TABLE ABC1;
Table dropped.
