mysql - How do I set a full date & time sql using java, and not just the date?

Question

I am trying to set a timestamp in my database using java, however in my table all I get is the date, and no time (i.e., looks like "2010-09-09 00:00:00").

I am using a datetime field on my mysql database (because it appears that datetime is more common than timestamp). My code to set the date looks like this:

PreparedStatement ps = conn.prepareStatement("INSERT INTO mytable (datetime_field) VALUES (?)")
java.util.Date today = new java.util.Date();
java.sql.Date timestamp = new java.sql.Date(today.getTime());
ps.setDate(1, timestamp);
ps.executeUpdate();

How do I set the date to include the time?

Edit: I changed the code as per below, and it sets both the date and the time.

PreparedStatement ps = conn.prepareStatement("INSERT INTO mytable (datetime_field) VALUES (?)")
java.util.Date today = new java.util.Date();
java.sql.Timestamp timestamp = new java.sql.Timestamp(today.getTime());
ps.setTimestamp(1, timestamp);
ps.executeUpdate();

Use java.sql.Timestamp and setTimestamp(int, Timestamp). java.sql.Date is date-only, regardless of the type of the column it's being stored in.
