Your settings are wrong. HideDateAttributeList[] takes the attribute ID from your content class. So if your product class has attribute ID "hide_date" then use it like:
If you want to hide your product at specified date then you need to extend product class with one more attribute (date or datetime datatype).
Go to Setup->Classes then choose Content class group. Edit product class and add one more attribute (Name: Hide date, Identifier: hide_date). Save your changes.
I have created an attribute in the product content class. After I was put the settings in content.ini.append.php i have run the runcronjobs.php still that product is visible.
