Rosbag Record Frequency

The ROSbag is stored in the exact path where the ROS-Driver module is launched (meaning that it will be stored on the robot if it’s launched from here). I can see that prior to loading the `rosbag play` command, the ROS time in rviz is set to 0, and it changes to the timestamp of the first message in my rosbag recording after I issue the play command (hence, it is indeed using simulated time, and not wall time).
