Hello ,

I tried to make the rosbag that is refering to tutorial in http://wiki.ros.org/rosbag/Tutorials/... .

But I could't make the bagfile and the error is the following:

use_sim_time set to true and no clock published . Still waiting for valid time.

I set the use_sim_time true , but I could't be successful.

Please help me.

The tutorial says nothing about setting or using the /use_sim_time parameter. Why do you think you need to set it?

I think that I need to set use_sim_time to true,due to the error mssage "use_sim_time set to true".

No; the tool is stating that /use_sim_time is set; not asking you to set it. I suggest you unset /use_sim_time and try the exercise again. (you can also clear all parameters by restarting the roscore)
