I freaking hate this type of troll... there are thousands of forums about this and yet people still think it is cheating....
added time

ok,ty,i didnt think i was trolling,i appreciate the response estrgon,i am new here and should have read more into it, i suppose, so i didnt have to offend the grumpies. no need for name calling.

It's definitely a lag, which can be created by the internet connections of one or both players. If you have a fast connection, as is widely available in the US, remember most of the world still makes do with dial-up. The server accounts for this, and only starts the clock once the player has received the move. Unfortunately, what you see doesn't adjust for this in real time, so it appears the opponent is getting time added when in fact the server is just showing you what his actual time is.
They only compensate 2 seconds

lol you dont know how many times people have accused me of cheating like this. they say I hacked the system and all that. they go on to curse me out and then block me.

Why did you call it troll? He was just asking a question.

This whas happening right now: I lost in a game with a better position, my opponent had 40 sec I had more than a minute. Then my opponent disconnected,(you know all gets gray and this dissconection box appears) It was not me there was nothing wrong with my connection.. and I waited for 40 sec my opponent fell on time.. and I waited.. and waited.. And finally..
GAME OVER - Lorisino vs. skakmadurinn - Lorisino won on time (-8). Your new blitz rating is 1772.
