          LPAD( EXTRACT( MONTH FROM CURRENT_TIMESTAMP ), 2, '0' ) ||
          LPAD( EXTRACT( DAY FROM CURRENT_TIMESTAMP ), 2, '0' ) || ' ' ||
          LPAD( EXTRACT( HOUR FROM CURRENT_TIMESTAMP ), 2, '0' ) ||
          LPAD( EXTRACT( MINUTE FROM CURRENT_TIMESTAMP ), 2, '0' ) || 
          LPAD( TRUNC( EXTRACT( SECOND FROM CURRENT_TIMESTAMP ) ), 2, '0' )
FROM      rdb$database
