Photos how to fix messed up metadata (geolocation/date & time)
Since I migrated my Photolibrary to iCloud Photo Library, information on my photos, such as geolocation and date have been messed up.
The original date & time is set off by a random amount of time, (months even) and the geolocation data seems to have been altered. (Miles off)
How can I restore the original data or fix the fotos?
