We present an exact waiting time Monte-Carlo algorithm (WTMC) to simulate systems that follow a dynamics given by a master equation with time-dependent rates. The algorithm can be conveniently used to investigate many particle systems driven out of equilibrium by time-dependent external fields. We illustrate the method for a one-dimensional Ising-spin system with Glauber dynamics. In particular we compute the probability distributions of the fluctuating work and heat. Our results are compared to analytical findings and tested against various non-equilibrium fluctuation theorems.
