What is map_load_time in nav_msgs/MapMetaData?

MapMetaData is in the OccupancyGrid message:

http://docs.ros.org/api/nav_msgs/html/msg/MapMetaData.html

The description says it is 'The time at which the map was loaded'- should this be the time the map was initialized? The time it was last updated (making it redundant with the header timestamp)?

@lucasw: I also have the same question as yours. Did you get to know anything about it?

I put some information into an answer to https://robotics.stackexchange.com/questions/24022/what-is-map-load-time-in-ros-nav-msgs-mapmetadata instead of here, making the migration extra complicated when it happens
