There was a problem hiding this comment.
lgtm. i think this should work for failed cases https://ci.ros2.org/job/ci_linux/20668/testReport/.
@jmachowinski thank you very much for your effort including weekend!
I will start the CI. (I will exclude ros2/rclcpp#2469, to verify this specific PR 1st.)

Added special handling for timers with a clock that has time override enabled. For these timer we should not compute a timeout, as the waitset is waken up by the associated guard condition. Before this change, the waitset could wait up, because of an expected ready timer, that was acutally not ready, as the time update to the ROS_TIME had not yet arrived.

This fixes the issues reported by #1142.
Fixed a bug that a ready override timer would not wake up the wait set.
Adopted the test to catch this condition.
