ISO 8601 date YYYY-MM-DD is Universal

I'm not sure of your definition of 'new', but ISO 8601 was first drafted in 1998 (26 years ago). It's been amended/updated a couple of times since, with the most recent significant update in 2019 (maybe that's 'new'?)

Incidentally, the YYYY-MM-DD format was originally established as a standard as part of ISO 2014 back in 1976 and this format was incorporated into 8601, so the idea has been around for a while.

In any case, the problem isn't standards. It's getting people to recognize and honor them. I don't expect to see the US move from it's oddball MM-DD-YYYY any time soon, for all the problems it creates :)

This format is the new standard, slowly being implemented around the world. It may be a surprise at first, but everyone who looks at it for a second or two realizes the 4-digit number is the year, and the light of recognition goes on. It is also the only easily sorted date format. And it prevents another "Y2K" debacle, where new software must be written to correct years of "but it's easier to only type 2 digits."

Okay. But how is this related to an issue with your Apple products or services?

That's the format I always use when putting dates in filenames, because it sorts properly.
