It does well with visual queues in the photo if there is no handwriting for dates or timestamps. It's definitely not perfect but it will get it so your photos feel chronological in the sense of "photo A is older than photo B".

The way to increase the accuracy is to add a birth year to face tagging so each photo has an anchor that the AI uses -- "This photo has joe, joe is born in 1950" and then it will look at how old joe is and if joe looks like 10 years old, it knows the photo is around 1960.
