The reason for it is that the millisecond timer returned by GetTickCount is the same timer synced between the server, the clients and GTA. This timer is used to sync things like traffic lights and wave heights etc. Unfortunately, SA is not designed to deal with a negative timer value and problems start to arise such as the one with the cinematic camera.

I agree though it's not very desirable for it to wrap to 0 and I will probably have to find another solution.
