in reply to perl's sleep function

I think perhaps your confusion was with the number format. You can use the underscore as a noop separator for numbers. So while 86400 might be written as 86.400 in some locales and 86,400 in others, in a perl script you can write 86_400. This is supposed to make really long numbers easier to parse for humans.
