Time-based currency

Time-based currency is a type of currency that is based on time instead of money - for example, you might use time as currency to pay for something instead of using money. So if you wanted to buy something, instead of paying money for it, you could pay with your time by doing something like working for the store for an hour instead. In some communities, time-based currency is an accepted way of paying for things.
