You are most likely setting the timestamp value by using setString or 
setObject with a string value on a PreparedStatement.  This is indicating 
to the driver that you want the parameter to have a string (varchar) type. 
This is not correct for a timestamp.  You should use setTimestamp or 
setObject with a third parameter indicating that the value is a timestamp. 
If you are unable to change your application for some reason, you can 
adjust the driver's binding behavior by using the stringtype=unspecified 
connection parameter described here:
