date and time field in dropdown menu on checkout

[LanFish1]

I need to implement a dropdown menu on checkout order page. In this dropdown menu there are date and time of  next two days  and is compiled from the user as the date to pickup a product onsite (pizza). So, for example if the user want to take a pizza today at 6.55 p.m. he/she has to choose from this dropdown menu in  the chekout order page.
How could I do?

I used shopper fields only for cart!
It works!
