Likely due to lag -- he actually made his move when he had 10-11 seconds left, but you're computer didn't get the notification until he'd run out by your count. Since your computer's count isn't the official count a correction is applied after each move which is why you see these clock adjustments.
where did his time come from?

Thanks for the explanation- I never knew my computers count isn't the same as the official count. Perhaps I need a new computer!
It's really the network latency that's causing it so I wouldn't go shopping just yet -- I believe there are three records of the clocks in any given game. Yours, your opponent's, and the server's. After you move your record is the most accurate, and it will update the servers to correct for the time it takes to get the message there, and the servers will update your opponent's to correct for the sum of the time it took you to update the server, and the server took to update your opponent. When your opponent moves the same things happens in revers so this time your computer's clock sees the biggest adjustment.
its all about lag. i have a terrible connection to live chess, i lag out after the very first move. i do far better in live chess 2 though =) www.chess.com/live
i move, then wait for him to move. 20 secs go by. then its my turn again, and ive actually lost like 3 seconds (due to lag) and he's lost like little, 1 second? and then i move and i lag out lol. Try Livechess 2! its good. Test it.
Can anyone explain this?. My opponent was down to 7 or 8 seconds. His time ran down to zero. I thought I'd won on time - Suddenly he's got another 10 or 11 seconds. We were playing 8 minute blitz with no "additional" time.
