Hi,

I need to play my bagfile with the -l loop parameter. However after the time is reset, I get a lot of these errors:

Warning: TF_OLD_DATA ignoring data from the past for frame openni_depth_optical_frame at time
1.30503e+09 according to authority unknown_publisher Possible reasons are listed at http://wiki.ros.org/tf/Errors%20explained
         at line 260 in /Users/usr/ros_catkin_ws/src/geometry_experimental/tf2/src/buffer_core.cpp

According to that wiki entry, one would send an Empty message the topic /reset_time. However, it seems that this topic has been removed a long time ago. What is the currently recommended way to deal with this time reset problem?

Are you publishing the clock? More recent tf implementations clear the buffer when negative time jumps are detected.

Yes, I am publishing the clock, also sim_time is being used.

/clock is definitely being published, but it seems to hang from time to time. This may be related to my question http://answers.ros.org/question/20053...

Hi J.M.T., did you figure this out? I have a very similar issue. The weird thing is that for me it all works, so the tfs are being published, but I just get lots of these TF_OLD_DATA messages cluttering up my terminal.
