What are these chess.com figures from my English Opening game? I am asking something that chess.com shows about the English Opening, based on a game that I recently played on chess.com 

Chess.com showed the following figures:

1.c4 e5
.. 
2.g4 e4 9.6 5.8

-White: 9.6
-Black: 5.8

What are these figures? It comes with Gantt Chart

As previously mentioned, these numbers are from the chess.com website, specifically from the "15|10" gamemode that I played in.

These figures seem to be common for all chess games. I think that it pertains to Chess Mega Base and Chess Analytics, which was already done, and clearly counted to some number. What is this rational number about.?
I believe you mean this (correct me if wrong):

This refers to time in seconds that it took to complete a move. So in this case (my game), it took White 2.5 seconds to make a  move, and 0.9 seconds for Black to respond. Then it took 19.7 seconds for White to make a move, and 1 second for Black to respond.
In your case, it took White 9.6 seconds to make a move, and Black 5.8 seconds to respond.
