And in a hundred years someone finds this old 2d-photo, and thinks we all looked like that and how common it seemed to loose two fingers, watching the guy on the left and in the back. Probably lumberjacks. They might be colleagues of the blind person to the right. Just like us watching the old b&w photos from a hundred years ago.
People rarely use them in real life, but ISO 8601 and RFC 3339 (both are almost identical) are the most natural ways of writing date and time. Just like how we write numbers, their components are written from left to right in the decreasing order of significance: yyyy-mm-ddTHH:MM:SS. I like it by default for precisely the reason you mentioned - sorting. It even helps quick visual comparisons.
