Dear all,
I just installed exiftool to correct the CreateDate of some photos taken in Canon's CR3 RAW format with a Canon EOS M50 on a Macbook (macOS High Sierra, version 10.13.6.).
Checking the current state of the file, I got:
exiftool -time:all -a -G1 -s IMG_0421.CR3
[System] FileModifyDate : 2018:09:24 03:52:38-07:00
[System] FileAccessDate : 2018:09:25 19:44:48-07:00
[System] FileInodeChangeDate : 2018:09:25 19:44:46-07:00
[IFD0] ModifyDate : 2018:09:24 03:52:36
[ExifIFD] DateTimeOriginal : 2018:09:24 03:52:36
[ExifIFD] CreateDate : 2018:09:24 03:52:36
But then, after typing
exiftool -AllDates-=9 IMG_0421.CR3
and checking again, I got:
[System] FileModifyDate : 2018:09:25 19:53:21-07:00
[System] FileAccessDate : 2018:09:25 19:53:23-07:00
[System] FileInodeChangeDate : 2018:09:25 19:53:21-07:00
[IFD0] ModifyDate : 2018:09:24 03:52:36
[ExifIFD] DateTimeOriginal : 2018:09:24 03:52:36
[ExifIFD] CreateDate : 2018:09:24 03:52:36
So only the FileModify/Acces/ChangeDates have been updated to the current time, but ModifyDate, DateTimeOriginal, and CreateDate remain unaltered.
I have also tried with a JPEG, and this works fine (ModifyDate, DateTimeOriginal, and CreateDate shifted by 9h in my example). So, is there an issue with the CR3 files? Do I need to do something else to change the time stamps for those files? Any help is appreciated.
What's the output when you run your time shift command?
ExifTool only has limited write capabilities for CR3 files. (Basically, you can only write XMP and some QuickTime tags.)

After typing
exiftool -alldates-=9 IMG_0421.CR3
I got the message
1 image files updated
which is somewhat true, since some of the time stamps indeed are updated. Unfortunately not those I wanted to change.

Thanks. Then I guess I can only convert the CR3 files to JPEG, and then try to fix the time shift at least for the JPEGs.
