I once worked in a software shop where all release packages had the Unix epoch timestamp in the filename. Yes, these sorted brilliantly making it trivial to find the last one. But good luck finding a build from a specific date/time.
Considering it uses day then month, 24hr clock, and distance in km, I'm guessing the reason why it's not "human readable in American" is because it's intended to be "human readable for pretty much everybody else"
