I need to create a table to store terms and conditions for purchase orders. Some of the attributes of a PO include payment terms. Quite often these will be 2 periods associated with these, the first is a period on which if you pay, you receive a discount, and the 2nd is when payment is due with no discount. I am thinking of storing these two attributes as time internals. What is the wisdom as to how to declare the type of these columns? -- "They that would give up essential liberty for temporary safety deserve neither liberty nor safety." -- Benjamin Franklin
