Timestamp Question

I have searched the archives and not found and answer to this question:

I am trying to use a Java Timestamp object to create a Postgresql
Timestamp(6) field.  I can insert a Timestamp but it only goes to the
millisecond(2004-07-10 12:59:59.123) I need it to the microsecond
(2004-07-10 12:59:59.123456).  Is there a way to do this?
