We present TECTLK, a logic to specify knowledge and real time in multi-agent systems. We show that the model checking problem is decidable, and we present an algorithm for TECTLK bounded model checking based on a discretisation method. We exemplify the use of the technique by means of the ”Railroad Crossing System”, a popular example in the multi-agent systems literature.
