Time stamps for the messages on /move_base/NavfnROS/plan

edit

Hello,

I am using ROS navigation stack on a turtlebot. The plan is getting published on /move_base/NavfnROS/plan topic. The plan looked like the following:

header:    
 seq: 13
 stamp: 
    secs: 23
    nsecs: 700000000
 frame_id: "map"
poses: 
  - 
    header: 
      seq: 0
      stamp: 
        secs: 23
        nsecs: 700000000
      frame_id: "map"
    pose: 
      <current_pose>
  - 
    header: 
      seq: 0
      stamp: 
        secs: 23
        nsecs: 700000000
      frame_id: "map"
    pose: 
      <next_pose>
  .
  . 
  . 
    header: 
      seq: 0
      stamp: 
        secs: 23
        nsecs: 700000000
      frame_id: "map"
    pose: 
      <goal_pose>

As it can be seen, each of the poses have the same time stamp (the same as the message's header). However, I'd need to get the time stamp associated with each pose as well. Is there a way?
