[Discussion] support ROS_TIME from /clock source

[NerdToMars]

Hi, I noticed the latest implementation has ros_time clock type, but it does not subscribe to the clock from /clock topic.

I am quite new to Rust and ros2, could you advise me on how to implement it? or is there a solution to use sim time with r2r?

Cheers.

I found a repo related to this ros2-rust/ros2_rust#325, but I think that's not suitable for this repo. I will close this issue for now. Although it might not be a good idea to implement the clock source in this minimal lib, feel free to reopen this to discuss more.
