The integer 20200806 is chosen solely for the purpose of human readability. If you actually wanted to store a date as an integer, you'd use the Julian day.

what human can't parse that? Sure it might take a half a second longer but it's hardly confusing.

For those of us whose professional lives sometimes require staring at directory listings full of filenames like "output-200003021342"... for the love of God, please just put the dashes in.

I have an infinite number of dashes, I'll send you a lifetime supply!
