ros::Time::now() always returns wall time [closed]

edit

Hey guys,

I have a very frustrating problem using Ros Hydro on ubuntu 12.04.. I have a Gazebo Simulation posting telemetry data and I use this in a node to create a tf-tree for the simulation. Now I tried to combine my tf-tree with some static transform publishers and noticed that my transform from the c++ node which subscribes to the telemetry is using wall time. The statics transform publishers are using simulation time.

I searched the web, set use_sim_time to true and trief some other things but ros::Time::now() in my c++ code always returns wall time, while the static transform publisher use simulation! This makes it impossible to use the transform together.
