The behavior of setDate() has changed starting with Oracle JDBC Driver
As result, time is inserted into DATE column if using setDate() method.

From Oracle JDBC Driver : the time is inserted as defined in the variables.
Oracle JDBC Driver or earlier : the driver sets the time to "00:00:00".

Sample Code :

PreparedStatement ps = conn.prepareStatement("insert into emp(empno, hiredate) values(1111, ?)");
Date cd = new Date(System.currentTimeMillis());
ps.setDate(1, cd);

Results :

Execute "select to_char(hiredate, 'DD-MON-YYYY HH24:MI:SS') from emp" statements,
the result is like follows.

- JDBC Driver and earlier version : 12-NOV-2014 00:00:00
- JDBC Driver and later : 12-NOV-2014 16:14:48
