A system, and a corresponding method, provides time synchronized playback and control of dissimilar data in a simulation architecture. The system includes a master site including a controller, and agents, implemented by the controller, where the controller directs the agents to control simulation data logging and playback; simulation sites, including: one or more simulation computers, where simulation events occur, a computer, where the agents control the simulation site to record the simulation data, and a local log that stores the simulation data as events, where the agents control the test computer to replay the events; a time reference system including a master site time stamp, local time stamp pair for each of the simulation sites, each of the local time stamps related to a master time stamp, and one or more time normalization factors. The time normalization factors relate times recorded for each of the events to an earliest recorded event and to a time of initiation of a replay command. In the system, a corrected event time, dtEvent, and a corrected system time, dtSystem, are established. Events are then injected for replay into the simulation architecture when the dtEvent and the dtSystem are equal.
