Here is the SQL that should calculate the end times.
SELECT Orders.Product, Orders.Description, Orders.Order, Orders.Qty, [Qty]*[Minutes] AS TotalMinutes, (SELECT MIN(ProductionDate) FROM Orders)+(SELECT Sum(P.Minutes * O.Qty) FROM Orders O INNER JOIN Products P ON O.Product = P.Product WHERE O.Order <=Orders.Order)/(24*60) AS EndDate
FROM Orders INNER JOIN Products ON Orders.Product = Products.Product
ORDER BY Orders.Order;
I hope you can modify the EndDate expression to get the start times. I think it might be just a duplication and change the <= to < but I didn't try.
I also expect your data has more than a single product and dates which won't be accounted for with this expression. You may need to add more criteria in the subquery to accommodate more dates and products.

Duane,
Here is a simplified version to make it easier to see.
Tables are linked by column product. Minutes are calculated by multiplying Product Table minutes of product times order qty.
Date format I use is mm/dd/yyyy if that makes a difference.
