This is taken straight from the documentation for srand

Frequently called programs (like CGI scripts) that simply use

time ^ $$

for a seed can fall prey to the mathematical property that

a^b == (a+1)^(b+1)

one-third of the time. So don't do that. 

I don't quite understand what the author meant, but this does not seem possible. Is this a mistake, or am I misunderstanding what is meant?

Thanks,
