pawn Code:

cell AMX_NATIVE_CALL Natives::GetTickCount(AMX *amx, cell *params)
    {
        return (int) (GetMsTime() % MAX_INT);
           //> #define MAX_INT                         2147483647 ( Max int. value )
    }

pawn Code:

unsigned long long GetMsTime()
{
#ifdef WIN32
    LARGE_INTEGER t;
    QueryPerformanceCounter(&t);
    return (t.QuadPart - startTime.QuadPart) / freq;
#else
    struct timespec t;
    clock_gettime(CLOCK_MONOTONIC, &t);
    t.tv_sec -= startTime.tv_sec;
    t.tv_nsec -= startTime.tv_nsec;
    if (t.tv_nsec < 0)
    {
        t.tv_sec -= 1;
        t.tv_nsec += 1000000000;
    }
    return t.tv_sec * 1000 + t.tv_nsec / 1000000;
#endif
}

So far i can see; plugin doesn't use SAMP's GetTickCount anymore. No 'GetTickCount overflow. Correct me if i'm wrong though..
