Actually it was the changes in version 1.21 on 2/13 that broke this. 
The cvs log for that change includes the following comment:
  - Removed need for SimpleDateFormat in ResultSet.getDate() improving 
performance.

My guess is the the code as written would work correctly for a 'date' 
column, but doesn't work for a 'timestamp' column.  Is there a reason 
you are not using getTimestamp() to get the value of the timestamp column?

thanks,
