I'm using ROS Wrapper for D455.
In this issue https://github.com/IntelRealSense/realsense-ros/issues/796, it says "Global Time Stamp is On by default". Does that mean the time stamp published on the ROS topic "/camera/color/image_raw" is ROS time?
I also found this post https://github.com/IntelRealSense/librealsense/issues/2188
It says that there are 4 kinds of timestamps in metadata: sensor_timestamp / frame_timestamp / backend_timestamp / time_of_arrival. Which one does the ROS Wrapper get?
Any help and explanation are highly appreciated!
