Is it possible to have absolute timers in ROS2? For example if the period is 60sec, I need the timer to trigger when the system clock reads “xx:xx:00”, i.e., on the full minute.
I tried to dig through the source behind
rclcpp::Node::create_wall_timer but could not find an answer.
If that is not possible, I would build my own using
TFD_TIMER_ABSTIME. Any tips on how to integrate that properly with ROS2?
