This doesn't declare any structures. It declares pointers, which you
aren't initialising. The correct usage is:
struct timeval t1;
struct timezone z1;
gettimeofday(&t1, &z1);
Also, note that you can pass NULL for either parameter if you aren't
interested in retrieving that information, e.g.
struct timeval t1;
gettimeofday(&t1, NULL);
will just return the time, and not the time zone.
