How 'bout a cheque dated 01/01/20...date goes stale but add 25 or whatever year 'appropriate' to the end?
Or maybe a Warranty/In service date written in the front of a vehicle glovebox booklet, good for 5 years from 01/01/20...year six, add an 21 and it's 'good' to 2026?
Not saying Banks or Manufacturers will get duped, more like small businesses cashing cheques/regular folks buying used cars or whatever else w/ 'doctored' paperwork...expect there's lots worse circumstances than these examples.
