Photos Library - Video Timeline all showing Jan 1 1900

Why are some photos dated as 1 jan 1900 when on "timeline" view

Thanks for the reports, with the help of @Coxeroni’s database I was able to track down a recent regression that was causing this. I’ve submitted a fix but not sure exactly which PMS release that will be but will let you know when that’s confirmed.

Acknowledged and probably also fixed.
