Hi,
Why do you need to use the advanced date picker for that ?
You could for example write that in the description of your product with text, no ?
You can of course create custom fields of the table "product" and of the type "advanced date picker" via the menu Display>Custom fields, so that in the product you can select the dates and then you can create custom fields of the table "product" and of the type "single dropdown" to select the hours.
But if it's just one date range information you want to provide to your users I don't see why you need custom fields ?
So I suppose you want to do something else, but I'm not sure what.
