$$ is uniqe as long as the system is not rebooted and as long as there is no overflow in the machines process counter. It might happen, but it's not very probable. I also didn't say that it's guaranteed to give you a unique filename. I just said, I would use it in the name. Not that I would use it as a name.

But regarding localtime: it's almost sure that you will get the same result quite often. At least there is a delay of 1 second you will have to have before the script might be started again.
