I want to publish a message with ros2 topic pub but use current time as a timestamp If I do not publish anything to the stamp or header fields then they are 0. I remember in ros1 you could publish with header:auto or stamp:now. Is there an equivalent for ros2?

This functionality was added to ros2cli recently in https://github.com/ros2/ros2cli/pull/749, and is available in ROS 2 Humble onwards!

You can do either:

{'header': 'auto'}

or:

{'header': {'stamp': 'now'}}
