Hello,

I am trying to graph robot's distance from a particular point over time. I have a bag file, and wondering if I can get the duration in the bag file. For instance, if I play a x.bag file, I have the following information:

[PAUSED] Bag Time: 1346096057.781698 Duration: 1.680327 / 19.253778

Is there a way to get that duration in a code?
