rosbag playback speed

Hi all,

We have some sensor data that are saved as .csv files (data+timestamp) from a robot, which does not run ROS. To run some algorithms, I converted once such file into a ROS bag file using a python script.

After setting the /use_sim_time parameter and when playback this bag file with rosbag play --clock abc.bag, all the data seems to be flushed at once.

I need to know what determines the natural play speed of a bag file. I thought it is done using the header.stamp

Thank you in advance
