It's about the rand problem that arises if you randomize 100,000 time_t values with the goal of 100,000 unique DD-MM-YYYY values. Consider it generically. Forget that it's a date function, and assume that you have a pool of input values for which output values only change for every 86400 inputs. You want to get 100,000 random (but hopefully unique) outputs given only 100,000 randomly chosen inputs. How do you randomize your inputs where the input pool is minimum 8.64 billion to guarantee that you *might* get 100,000 unique outputs.
