Thanks a lot! This is great! Would you mind explaining the ~~ trick? localtime returns a list, so I would have concluded that applyiing ~ to this list would force it into scalar context, so it would bitwise negate the number of elements in the list. But this is obviously not done, because just by trying out your code, I see that it works.
