This script does not change timezone, it change datetime. That is not enough, i.e., Google Photo could show file with invalid time. Use also . exiftool "-timeZoneOffset=-4" . (assume photo taken in UTC-4)

To be EXIF >2.31 compatbile, use -OffsetTimeOriginal=-04:00. timeZoneOffset is not part of any official standard
