[PRESTASHOP 1.7.3.3] Webservice - get product list between two date

[a17000]

Hi,

I have find a bug , I think :

I do this request via WebService to get product list modified between two dates :

$xml = $webService->get(array('resource' => 'products&date=1', 'display'  => "[name,price,code_zone,wholesale_price,description,reference,id_category_default,id_category_default,id,date_upd,date_add]",
"filter[date_upd]" => "[2018-12-03 16:40:48,9999-12-31 00:00:00]","sort" => "[date_upd_ASC]"));

And I got a list of products...but the first product have date_upd = 2018-09-04 14:35:17...

Why ????

If I try with anoter date like this :

$xml = $webService->get(array('resource' => 'products&date=1', 'display'  => "[name,price,code_zone,wholesale_price,description,reference,id_category_default,id_category_default,id,date_upd,date_add]",
"filter[date_upd]" => "[2019-01-29 16:40:48,9999-12-31 00:00:00]","sort" => "[date_upd_ASC]"));    

the output is correct only product modified after 2019-01-29 ..

any idea?

Thanks,

ps: I have  4000 products in my table ps_product
