Money is already based on time. When you go to the store and buy some fruit, you pay for it, but you could also take the TIME to plant some of your own and grow it. When you buy furniture you are paying for something you could take the time to build, and each part you would need is also based on time (you could chop your own wood, etc.) This applies to services too, obviously. You could learn to be an accountant, but you can also pay someone to do it for you, you're paying for their time. When you boil it down, just about everything you buy is based on time.
