Time Bank

From the website:

Through Time/Bank, we hope to create an immaterial currency and a parallel micro-economy for the cultural community, one that is not geographically bound, and that will create a sense of worth for many of the exchanges that already take place within our field—particularly those that do not produce commodities and often escape the structures that validate only certain forms of exchange as significant or profitable.

Time banking is not barter. Barter economies have been in practice throughout history, but the idea of using time as a unit of exchange only appeared shortly after the Industrial Revolution. The origins of time-based currency can be traced both to the American anarchist Josiah Warren, who ran the Cincinnati Time Store from 1827 until 1830, and to the British industrialist and philanthropist Robert Owen, who founded the utopian "New Harmony" community. While both systems are based on the principles of mutualism and the labor theory of value, Josiah Warren's currency was explicitly pegged to time as a measure of specific goods or labor.
