The time stamp in the header of the message camera/depth/image_raw is occasionally set to zero.

Run one demo given in the turtle_gazebo tutorial at http://wiki.ros.org/turtlebot_gazebo/Tutorials/indigo/Explore%20the%20Gazebo%20world.

$ roslaunch turtlebot_rviz_launchers view_robot.launch

The time stamp is the header of the message camera/depth/image_raw is expected to monotonically increasing but occasionally is set to zero as shown in the attached image.

a few pull requests (#410, #540) that fix this problem were merged recently but they're target at kinetic and jade. I don't know if it will be ported to indigo though. @j-rivero

Thank iche033 for the info. I was actually running the demo on ROS kinetic but I installed the Ubuntu official gazebo_ros package via "apt install", so I guess that it may not contain the fix, right? Do you know when the fix will make the way to the official package?

[iche033]

I see, yes it's likely that a new version has not been released yet. I'm not sure it'll be done. It'll be up to the maintainers.

The new version 2.5.9 of gazebo_ros_pkgs for kinetic was released some days ago. Those packages are ready in the shadow repository and will be updated with the next sync that will be announced here

[renweizhukov]

Thank j-rivero for the info. Look forward to the kinetic next sync.

Duplicate of #490 (fixed). Comment to re open this issue if it still occurs on supported ROS distros.
