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:
