maybe your opponent moved really fast and you moved really slow. If he used less time than the lag time for each move (possible with premove) it might appear to you that his time is going up even though it is not.
unlimited time?????

If he's using less time than the lag time for each move, it would appear to go up from where it counted down to on that move, but would never actually increment to a higher value than the time that was left on the previous move. That said, I suspect you're right Loomis -- the game had a 10 0 time limit so increment time doesn't explain this, it's likely a product of lag correction possibly exascerbated by premoves.
