Regarding Datetime datatype

Hi
I am reading a Datetime datatype column from SQL server table. For some reason it is not printing hours, minutes seconds. How can I make my program to print hours, minutes seconds also.

Date s = resultset.getDate("last_modified_time"); // where last_modified_time is name of Datetime datatype column
System.out.println(s);

Thanks
Vivek

Generally, if you want to change the way a date is displayed, you can use java.text.DateFormat. But I looked at the documentation for java.sql.Date. It says:
To conform with the definition of SQL DATE, the millisecond values wrapped by a java.sql.Date instance must be 'normalized' by setting the hours, minutes, seconds, and milliseconds to zero in the particular time zone with which the instance is associated.
I take this to mean that even if you use DateFormat, it will not provide the time value as you'd expect. Try using java.sql.Timestamp instead.
 
It is sorta covered in the JavaRanch Style Guide.
