} [1533]The subtle difference of getTime() between 1.3.1 and the later ones
By Anonymous on 2005/09/13 06:44:18 Rate
Note the subtle difference between 1.3.1 and the later ones: The following lines appear in the 1.3.1 Javadoc, but were removed in subsequent version.
The getTime method will return only integral seconds. If a time value that includes the fractional seconds is desired, you must convert nanos to milliseconds ( nanos/1000000 ) and add this to the getTime value.
If your code needs to run on JDK 1.3 and later, you??ll have to do this:
java.sql.Timestamp timestamp = resultSet.getTimestamp ( 1 ) ;
long millis = ( timestamp.getTime ( ) / 1000 ) * 1000 + timestamp.getNanos ( ) / 1000000;
java.util.Date d = new java.util.Date ( millis ) ;
