I’ve decided to use the standing Tooling WG Breakout Session for April 2 on the ROS Events Calendar to continue coordinating work on rosbag2 time control functionality for Galactic. There have been a few different overlapping and uncoordinated threads of work that can’t all be merged without working together, so I’m setting aside this time for interested parties check in and continue making coordinated progress towards a cohesively designed solution.
See Design for rosbag2 handling of clock/simtime by emersonknapp · Pull Request #675 · ros2/rosbag2 · GitHub for the design
And [Epic] Rosbag2 playback time control and simulation time · Issue #696 · ros2/rosbag2 · GitHub for the ongoing work
