Measuring System Latency

I'm controlling a turtlebot, and would like to measure the latency of the system.

Specifically, I'd like to see how long between when a frame is taken on the connect, to when it is read by the subscriber in move_base, and then to when the cmd_vel corresponding to it is published.

Does anyone have an idea of how I might measure these times?

Thanks
