Hello,
is there any possibility to synchronise ROS and Simulink with the ROS time?
Thanks!

What exactly do you mean by this?
There's a real-time pacer block on the File Exchange, which is very common for Simulink-ROS desktop applications.
This block will essentially slow down your Simulink model using your host CPU clock; otherwise, Simulink will just run as fast as it can. Hopefully that was your problem and I understood it correctly?

I would like to use the ROS /clock which is generated by Gazebo in Simulink. It should be possible faster than realtime.
Thanks for you help!

I see.
Well, you could subscribe to the /clock topic and grab the times from there (or otherwise grab them from the timestamp data of any other message coming in).
You can use that in a Triggered Subsystem. This subsystem will execute only when its control signal is triggered; for example, when the ROS clock time exceeds some value.
