Which is why we have UTC.

See UTC.

> or out of order by minutes for individual devices.

which is alright, compared to the sort by time added to album.

Yep. I've seen UTC.

And I'm invariably the only geek whose photos are timestamped in UTC because I set devices that way (except for phones which I can't), or who knows that the metadata doesn't even record the TZ until a recent EXIF standard update, 2.31 released last fall, added support.

Wikipedia still says "There is no way to record time-zone information along with the time, thus rendering the stored time ambiguous." It'll be a while for cameras to catch up.

Most of my friends and family take their photos with Android, iOS devices and Google Photos seems to have fixed this issue and all of my photos have a timezone field. Here is an example of a recent one: https://i.imgur.com/8AFgKs3.jpg

Not sure how it's done, but I also don't have this problem on iOS. Apple Photos seems to sort by UTC, not sure if it uses embedded TZ in photos or the GPS in EXIF, but whatever it's using, it seems to work fine for me.

I’m talking about many people with diverse cameras.

Apple Photos sorts photos by UTC, today, I assume by using the GPS information inside EXIF. There is no confusion between photos taken in different time zones.

I do a lot of photography from jets, and the photos are sorted just fine, while the time zone changes all the time.
