"Detected jump back in time. Clearing TF buffer" problem

[dchang....@gmail.com]

When trying the first example in  Chapter 8.2 of ROS_by_Example_hydro_volume_1, I met a TF problem. After firing up "roslaunch rbx1_bringup fake_turtlebot.launch" then "roslaunch rbx1_nav fake_move_base_blank_map.launch", I saw a log "Detected jump back in time. Clearing TF buffer." and the application has stopped.

Does anyone help me to solve this problem? All of my setting are followed by this book and all the examples in Chapter 7 can run normally.

Thanks in advance.

Hi,

I can't reproduce this on my Ubuntu 12.04 machine running ROS Hydro and
I haven't seen it reported before. The only idea I can suggest is to
restart the roscore process and try again. Otherwise, try posting the
issue on http://answers.ros.org if you haven't done so already.

Hi, Patrick,

Thanks for your reply. My environment setting is Ubuntu 14.04 and running ROS Indigo. 

I will try it via running ROS Hydro.

Ah, I thought you were running ROS Hydro since you were using that version of the book.  I just tried it under Ubuntu 14.04 and ROS Indigo and it worked fine there too on my machine.
