Rather than using Calendar.getTime() we can use java.sql.Timestamp class to get the time stamp which gives date and time till millisecond precision.
System.out.println(new Timestamp(System.currentTimeMillis()));
Above will give you current timestamp in this format: 2010-07-27 16:37:45.39
System.out.println(new Timestamp(System.currentTimeMillis()));
Above will give you current timestamp in this format: 2010-07-27 16:37:45.39
