WebHi everyone, I am very new to using ROS2.0 (Foxy). Im working on a project that uses a publisher/subscriber to send messages. I need to know the time in between when messages are received (i.e. message 1 comes in at time 0, message 2 comes in at time 10, therefore the amount of time between the messages equals 10 seconds). WebWhen a ROS message contains a header field of type std_msgs/Header, you can use this block to update the frame_id and stamp values in its header field. During each sample hit, the block updates the frame_id and stamp fields in the header. The accuracy of the timestamp depends on the step size of the solver.
