int32 GetTickCount / GetGameTickCount

Right now i have to use following:

    double d = (FPlatformTime::Seconds() * 1000.0);
    uint64 ui64 = (uint64)d;
    int32 i32 = *(int32*)&ui64;
    return i32;

Or i can use this, but it is only for Windows:

return (int32) ::GetTickCount(); // DWORD GetTickCount();
