The big difference is of course, is that the java.sql.Date is "A thin wrapper around a millisecond value that allows
JDBCto identify this as a SQL DATE (JDK1.3.1 doco)" - it subclasses java.util.Date so certainly holds time ;)
In relation before that, java.util.Date holds a specific instance in time - without timezones coming into play - in
realitythe amount of seconds since Unix birth or 1970 or whatever it is. I'm not sure about the JDBC driver and backend
interaction,but I'd be using a GregorianCalendar or Calendar instance instead, which is more suitable for manipulating
datesand times. I'm not sure if the setObject() method caters for this though.
