Hi, when I play rosbags, sometimes I feel that the whole __timestamp / clock /use_sim_time__ is hard to grasp and has many pitfalls and corner cases where it doesn't work. When I use __rosbag play --clock__ and set the rosparam __use_sim_time=true__ things work 90% of the time, but occasionally, especially with TF, this approach seems to be unreliable. Am I the only one that had this kind of problems? Am I missing something? I would like to implement an additional option for __rosbag play__ to change the Header/stamp field of each message to avoid the simulated clock. I am not asking if this is technically feasible (because I know how to implement it), I wonder if this is even __desirable__ and if the community would find it useful; as I said, maybe the rest of the community is just happy with the default approach.
