Please include exact information as outlined in the issue template: what you are using (links to repos including the branch name), your platform, what you are doing and a 1-to-1 of the error message / stacktrace you are seeing.

when i want to use the clock module, i got the error:

from rclpy.clock import ROSClock

ModuleNotFoundError: No module named 'rclpy.clock'

from rclpy.

Assuming that you are using the latest release (which you haven't been able to clarify) this is expected since the Python module rclpy.clock has been added after the latest release. You will need to use the latest code from the master branch to use this feature.

I will go ahead and close the ticket.

when i use the latest code from the master branch, i got this error:
