Clock not working!

I've lost a number of games thanks to time being added to opponent's clock, even though the game was set up with zero bonus time. Frustrated and confused. Am I misinterpreting the code? For example, the last game listed as a 5/0 wound up this way. The clock had run out yet time kept getting added to opponent's clock. Wtf?

Pretty hard to go for the win in a timed game if the clock malfunctions, you can have a decisively winning position and still lose, thanks to this problem. I also never saw any lag bar indicators, not once.

They sit to the right of the name I do believe, and to the left of the time.

I think they make better lag bars in Sweden. The only bar I see is the one I'm heading to for a scotch later on.

See an explanation of lag here.

Thanks for the explanation TadDude. If the lag bar warning was at least visible I could then opt to avoid those matches, but such is not the case. Just lost another match unfairly and there was definitely no warning bar in sight. The snow's a fallin' on da trail...

The clock malfunctions every game--jumps ahead.  I win on the board and lose on the clock.  Congratulations to the chess.com programmers for their ineptitude.
