type of value when import

i understand some items name can be import : `product_name`,`product_code`,`product_tax_id`,`product_quantity`,`product_min_per_order`,`product_max_per_order`,`product_weight_unit`,
`product_dimension_unit`,`product_published`,`product_type`,`product_description`,`product_modified`,`product_created`

Is there a documentation about which type ( int, string ...) are those items or where are they locate in database ?

Does hikashop_product is the name of the table that is ojly use when import export ?

`product_created` value is '1373148070' what does it mean ?


thank's

they are located in hikashop_product

this is the structure of the table:
pastebin.com/e2qDgTyC
It's messy but readable

product_created has the value of the unix epoch timestamp generated with the php code:

<?php
echo time();
?>

thank's
