Photo dates and sorting
I have pictures taken in other time zones where the camera or iPhone was not showing the correct local time. I used "adjust date and time" to make the time correct. However, I cannot get the to show in the order "oldest first." So, for example, we visited an art museum and a national park. My iPhone photos are dated correctly. Camera photos, after import, were adjusted. But the camera photos show up in the wrong order. This occurs both in the main library of photos, and also in the album that I created - even when I choose "oldest first" in the Sort options. How do I get the photos to show up in the correct order. (Not using Catalina, because too many apps aren't updated for it.)
