I bought one of those librarian’s date stamps a while ago from Staples. I use it to date my projects and other things; it’s fun. There was one problem, though. The date it could stamp was in MONTH-DAY-YEAR format, as in “NOV 05 2007.” Using computers, I find it organizationally beneficial to label dated files and folders in a YYYY-MM-DD format, as in “2007-11-05,” and wished my stamp reflected this general-to-specific date format outlined by the ISO 8601 guidelines. So I changed the order of the loops, and photo-documented this easy hack. Link to Flickr set.
