Why is TimestampBehavior in Yii2 throwing an error?

Question

MySQL

// behavior:
'timestamp' => [
                'class' => TimestampBehavior::className(),
                'createdAtAttribute' => 'created_at',
                'updatedAtAttribute' => 'updated_at',
                'value' => new Expression('NOW()'),
            ],

Mistake:

SQLSTATE[22003]: Numeric value out of range: 1264 Out of range value for column 'created_at' at row 1
The SQL being executed was: INSERT INTO `category` (`parent_id`, `title`, `mk`, `md `, `visibility`, `created_at`, `updated_at`, `created_id`, `updated_id`, `slug`) VALUES (NULL, 'Stepper motor controllers', '', '', 1, NOW(), NOW( ), 1, 1, 'kontrollery_sagovyh_dvigatelej')

Date fields

int(11)

,
did everything according to the manual, out of sync in one day, plus does not add an update date if I just write

return [

            TimestampBehavior::className(),
            // ...

Попробуйте добавить в поведение

'value' => new Expression('UNIX_TIMESTAMP(NOW())'),
