custom product field date time

-- HikaShop version -- : 2.3.4
-- Joomla version -- : 2.5.8

Hi
1) when i try custom field and use date picker , hikashop show me incorrect date format !!


2) Is there a way to support data and time in custom field type instead the only date ?


3)
the HKS date picker come from dynarch.com/mishoo/ locate in joomla\media\system\js\calendar-setup-uncompressed.js . The date format i think must follow php syntax find in php.net/manual/en/datetime.format.php
so how can i use " Y-m-d H:i:s" instead d/mY ?



thank's

So i can change the date picker by another one that support date !!
Great !! Thank's a lot .....
