zlbing commented 1 year ago

we found the parameter "time" that not used in canTransform function, how to understand it, maybe is bug? https://github.com/ros/geometry2/blob/309814fd7d55d874f9bac40b2cc8669a5b86f3c5/tf2_ros/src/buffer.cpp#L120C39-L120C43

Please provide an example of how time is not used. It's passed through to canTransform in https://github.com/ros/geometry2/blob/309814fd7d55d874f9bac40b2cc8669a5b86f3c5/tf2_ros/src/buffer.cpp#L135 and https://github.com/ros/geometry2/blob/309814fd7d55d874f9bac40b2cc8669a5b86f3c5/tf2_ros/src/buffer.cpp#L141
