General equilibrium is timeless, and without outside money, the price system is homogeneous of order zero. Some ﬁnite horizon strategic market game models are considered with an initial issue of flat money held as an asset. For any arbitrary ﬁnite horizon, the solution is time-dependent. In the inﬁnite horizon, time disappears with the initial issue of flat money present as circulating capital in the fully stationary state and the price level is determined.
