Apriltag pose timestamp always zero? #54

Hi, I've been playing around with this package to try to get it working for my FRC team. My specific application requires me to get the time at which a tag's pose was detected.

I'm using rclpy to access tag detection data from isaac_ros_apriltag. This returns tag detections as PoseWithCovarianceStamped objects. However, when I try to access the timestamp of the pose, it is always zero. Could I be doing something wrong? Without the timestamp I cannot accurately compensate for latency.

Thank you.
