The random generator is seeded in every iteration of the inner loop, but each iteration takes a time << 1 second (I don't know the actual amount but it's just very small), so time(0) is very likely to be the same over all the iterations, and thus rand() gives you the same thing.

Seed the random generator outside the loops.
