> There is no year 0, month 0, or day 0 in the notation scheme used by Derby
> timestamps. We should state this in the Reference Guide section titled
> "TIMESTAMP data type". The following script shows this:
> {noformat}
> connect 'jdbc:derby:memory:db;create=true';
> create table t( a timestamp );
> -- fails because year, month, and day must be positive integers
> insert into t values ( '0000-00-00 00:00:00' );
> insert into t values ( '0001-00-00 00:00:00' );
> insert into t values ( '0001-01-00 00:00:00' );
> -- succeeds
> insert into t values ( '0001-01-01 00:00:00' );
> select * from t;
> {noformat}
