Using the WebAPI how can i see the total elapsed seeding time?

[rille111]

Looking at /gui?list and also gui/?action=getprops  

Still I am unable to discern the field for total elapsed time. I do see it in the regular UI.
I can find out the actual current seeding ratio, but not the seeding time. The seeding_time from props is the goal, not the actual value.
I can see when torrent was added and completed (unix epoch timestamps) in the ?list request. But this is uninteresting.
 

Im building an automated tool to
* customize seeding goals based on tracker regex matching
* unpack and copy finished torrents
* auto delete them when goals are reached
