Title: Updating values for OffsetTime* Tags and TimeZoneOffset updates ThumbnailOffset
Post by: jotzet79 on April 24, 2020, 09:46:27 AM

Hello,

When I'm updating an Image file via JSON using Tags

Code Select

[{
  "SourceFile": "/Users/xyz/Pictures/Events/IMG_2086.JPG",
  "EXIF:OffsetTimeOriginal": "-04:00",
  "EXIF:OffsetTime": "-04:00",
  "EXIF:OffsetTimeDigitized": "-04:00",
  "EXIF:TimeZoneOffset": "-4 -4"
}]

and executing the update via the following Command Line Params

Code Select

exiftool -config ./System/exiftool.cfg -V5 -G0 -a -ee -u -b -j=upd.json /Users/xyz/Pictures/Events/IMG_2086.JPG
it apparently also updates "EXIF:ThumbnailOffset": 2998, -> "EXIF:ThumbnailOffset": 3050,

When I choose different tags to update this doesn't happen. :-\

Thank you for some insights,
Joachim

Hi Joachim,

See FAQ 13 (https://exiftool.org/faq.html#Q13) for an explanation of this.
