Isaac ROS nodes are publishing messages with the timestamp since I started the container / I started the Jetson.
However real time is different:
Time inside container matches real time
And the rest of my ROS nodes are publishing with the correct timestamp
How do I make Isaac ROS nodes publish messages with the same timestamp as the current time?
Thank you
Hi @eloi3
If you are looking for a real-time response on your Isaac ROS package, you can use the PREEMPT_RT Kernel for Jetson
This mode reduces the latency on the packages and makes your device real-time.
Hi,
It is not a latency problem, as the real timestamp is 1720103976 and isaac ros nodes are publishing 4971, which is the time since the jetson was started.
I think the issue is that the isaac ros nodes are not using the time since epoch but the time since the device turned on. If I reboot the jetson, it will start at 0 again.
Is there any way to change the clock source? Thank you
Hi @eloi3
To better support you, can you reply which setup and camera you are using? And which demo and nodes you are running?
