How can I get real-time/simulation-time ratio?

Hi, I am doing a simulation in Stage, and I want to compare the performance with and without stage window. With GUI there is the clock, which shows the real-time/simulation-time ratio. But, how can I get this value without using stage GUI?

Haven´t worked with stage, but I assume it also uses the /clock topic to provide consistent timing across all nodes when running simulation (like gazebo does). In that case, you could listen to the /clock topic and get all time information you need from that. See also the Clock documentation on the ROS wiki.
