If it is what I think you mean, then you are talking about the 'time per move' for each player.
White bar is for light pieces player, black bar is the time per move for dark pieces player.
You can test it yourself. During a game wait first 10 seconds for a move and on the next move wait 20 seconds. Afterwards, hover the cursor above the last 2 bars of your respective color. Will they show 10 and 20 seconds ?
