Captured frames are published with the generated timestamp (ROS Time). However, for better synchornization, for example, when using two cameras for disparity map construction it is better if timestamps reflect real frames captured time.
[This question on stackoverflow] (https://stackoverflow.com/questions/10266451/where-does-v4l2-buffer-timestamp-value-starts-counting) demonstates that v4l2 drivers do not use realtime clock, so it should be converted somehow.
