"Invalid default value for 'data_registrazione'"
Base on error you have issue on the following line

data_registrazione' => array(
'type' =>'timestamp',
'constraint' => '6',
'default' => CURRENT_TIMESTAMP

CURRENT_TIMESTAMP is = "1970-01-01 00:00:01" for example and cannot put in field that has 6 constraint.

There are those who tell lies with meaning behind them and those meaning less lies!
