It's not a glitch--it's lag.

Time usually has a beginning, middle, and end. At a set rate of speed which as we know is still up for discussion, but for the most part, a set rate of speed.
In live chess time has a beginning, middle, back, middle, back, end, back, end, back, and end. It is pretty easy once you get the hang of it.
I just finished playing a 3 minute blitz game with no bonus time added.My opponent's clock reached 0.00 so i assume i win.The computer does not acknowledge this so i wait,and sure enough his clock now reads 7.5 secs as he makes a move.I move quickly,wait again as his clock hits 0 again,which it does.Still nothing from the computer.He then resigns,with his clock now reading 9.6 secs.What exactly was going on there??
