Strange Metadata in Microsoft OneDrive

[Bernie]

Hi,
thanks to the help I received in this forum I was able to resolve most of my tagging problems when uploading my photos to MS OneDrive.
But now I have a behavior I can't explain.
For some photos OneDrive generates correct date tags (like Testfile01.jpg, see left side of the screenshot attached) and others not. My problem is that when I check them with exiftool everything seems to be alright.
In the attached picture you can see a screenshot how OneDrive shows the tags compared to exiftool. In Testfile01 there is a "Date Taken" tag which doesn't exist in Testfile02. And I don't know why.
I also compared the two files with jExiftoolGui (see attached PDF). But also there I see no differences that could cause a different interpretation (from my opinion).
Does anyone had such a problem before or knows what could be the reason?

Here is the output from exiftool in textform:

First, try adding -G1 to your command to make sure those tags are in the correct location.  You should see something like this

Code Select Expand

[IFD0]          ModifyDate                      : 2022:10:13 08:17:03
[ExifIFD]      DateTimeOriginal                : 2022:10:13 08:17:03
[ExifIFD]      CreateDate                      : 2022:10:13 08:17:03
If the tags are in the correct places, try this command to see if there's problems with the structure
exiftool -g1 -a -s -warning -validate /path/to/files/

Otherwise, there's not much else to do, it would be a OneDrive problem.

Thanks for your help.
I tried it and...

-G1 gives the following output:

bernie@Bernie-Mint:/media/bernie/Daten/tmp/Mist$ exiftool -time:all -s -G1 .

[ExifIFD]       CreateDate                      : 2006:03:18 18:00:11

With the second command I get some warnings. But I don't know what they mean or how I could eliminate them...

All of those warnings would be fixed by writing anything with ExifTool.  In general, even though the TIFF specification mandates even offsets for stored values, I don't think that any reader really cares about this, so it is unlikely that this is related to the problem you are having.

Hi Phil.
this hint All of those warnings would be fixed by writing anything with ExifTool was the solution.
First I copied all the Exifdates to the Filedates (because some of the Filedates weren't correct)

Code Select Expand

exiftool '-FileModifyDate<DateTimeOriginal' .
Then I copied back the Filedates to the Exifdates to correct the offset

Code Select Expand

exiftool '-FileModifyDate>DateTimeOriginal' .
Moved them to OneDrive and: Voila
All of them are now in the correct timeline.

Thanks a lot.
