When using ignition SITL simulation with NO_LOCKSTEP, the SITL PX4 fails to update the IMU data from Ignition Gazebo.
The timestamp for the IMU data is taken from the ignition message:
- In LOCKSTEP mode the clock from the ignition simulation and the one from PX4 SITL are synchronized, hence everything works fine
- In NO_LOCKSTEP mode, those clocks are not synchronized anymore, so the timestamp for the IMU data should not be the one from Ignition but the current time in PX4 SITL when receiving the message.
