I've just tried out the Photos app (updated version in High Sierra) and imported a stack of photos from a USB drive. Most are fine, but about 10% have the wrong date in Photos, but the correct date shows if I check the actual file properties in Finder. In Photos, it gives me impossible years like 1902, 2018, 2032. It has nothing to do with the camera date. All of my files have the correct date when you view the info in Finder or Windows Explorer. In Photos: Date: 23 Feb 2023 6:33:59pm In Finder: Date: 08 Jan 2013 11:40am What is going on?
