Yes, that is kind of crazy really.
But what is weird, if they are speeding up the clock would you foot alot
faster and throw grenades faster etc?
I seen the speed hack only 1 or 2 times and didnt' remember seeing them fire
faster but it might be hard to tell dunno..

Usually the client's system clock is running faster (slower?) than
normal, I can't remember which way the system clock needs to go to make
the game engine think time is passing more slowly. Your client machine
is running faster than normal so normal movement speed on your machine
become high movement speed on the server (who's running on a different
clock speed).
If the client's game engine is ticking faster/slower than the server's
game engine, the client will be able to move larger distances over the
same amount of time. It's sort of like the reverse of Einstein's theory
of relativity. Distances become smaller for people who are moving
faster in time (or something like that).
Surely this is where it should be caught by the engine. I don't mean
the engine should ban/stop/warn the player, but that the engine should
know that even though the cheater is saying this is tick 3000, the
server is only at tick 2000, and thus the movement should not be
processed until tick 3000.
i.e even if the game plays faster on the cheaters computer, those
extra ticks should not be processed inline by the server and should
not be propigated to the other clients until it's the right time.
Obviously I am very wrong, because if it was that easy it would be
fixed ... google is my friend, I go visit him now ;)
