Dave, please find a test attached. I guess, I can shed some light on it in the meantime. To me it seems, that setDate()/getDate() indeed ignores any time values (hh:mm:ss.s) but parses the day-part only (yyyy-mm-dd). At the same time, setTimestamp()/getTimestamp() behaves correctly. (Note: in Postgres Date is Date only without Time, while Timestamp obeys the Time, I was not completely aware of this. I thought the only difference between Date and Timestamp is Milliseconds vs. Nanoseconds.) On the same time java.sql.Date and java.util.Date support time information and in fact you can handover a java.sql.Date parameter to a Timestamp field. This is the part when I get confused: the timestamp field holds time information, the java.sql.Date parameter holds time information -- still it is cut off in the middle. Now I would like to suggest a couple of small changes: a) allow java.util.Date in setObject() and convert it into java.sql.Timestamp automatically b) keep the time info whenever setting/returning java.sql.Date to/from a Timestamp field However, for the moment I am fine as I understood now the need for using java.sql.Timestamp when working with time. Thank you a lot and best regards Andreas PS:
