The intention of the paper is to show the applicability of the general categorical framework of open maps to the setting of partial order models with a dense time domain. In particular, we define a category of timed event structures, where the morphisms are to be thought of as simulations, and an accompanying (sub)category of timed pomsets which provides us with a notion of open maps. Then, we show that the abstract equivalence obtained from the framework of open maps coincides with a timed extension of the well-known trace equivalence based on Pratt’s partial orders.
