Tue Sep 09 00:00:00 GMT+08:00 1980how do you insert and retrieve your Data ?alright, Hibernate it is... I don't know how it handles Timestamps, but I know some JDBC drivers don't set the time well when passed a Date instead of a Timestamp. Take a look at Hibernate type mappings and such, and define your column as timestamps. You may need to modify your mapped classes too...
