Odd functionality but it works
I have some photos from a friends camera whose date is years off. I tried to use Terminal to change the Created Date but for some reason it would only change the Last Modified date.
I downloaded this application and found that it edits either the Modified Date or the Created Date and makes them match. That being said I used Terminal to update the Modified Date then dragged the files to this application and it quickly edited the Created Date to match the newly edited Modified Date.
Like I said, it works but its behavior is a bit odd, and I suppose limited.
With Family Sharing set up, up to six family members can use this app.
