wrong time on photos in shared album.
I recently returned form a trip to Vietnam. All my photos in the Photo app on my Mac have the right time (Indochina time) and location. Created a shared album, but all the photos in the album have the wrong time, specifically, they are showing PST. Example: a photo in the Photo Library shows a time and date of Feb 24, 4 pm. The same photo in the Shared Album says the time is February 24, 1 AM, or 15 hours earlier, although the location info in both copies shows Hanoi. Any ideas on how to remedy this?
