TimeDate Shift is not behaving as expected.

[PicklePanic]

Is it me? or is it the gui?

how do I change the dates without the gui?

sorry for the newbie questions

I am not familiar with the GUI, but shifting datetimes is usually done by specifying the shift as follows: YY:MM:DD hh:mm:ss.
So if you want to shift by 3 days, 14 hours three seconds you'd specify 3 14:00:03 (or 86:00:03) for the shift.

Hope this answers your question.

When using this in windows (which may be the wrong syntax)

exiftool.exe 1.jpg "-DateTimeOriginal+=5:10:2 10:48:0"

I get this response

    0 image files updated
    1 image files unchanged


I was not able to get Shift to work, I need to try the command line.

Have you already tried prefixing the numbers with zeroes so all parts are two digits?
Also, does this file have a datetimeoriginal tag at all?

I have tried a variety of things.


Mostly the tool looks like this.

a few times it did populate itself correctly, but I am unable to replicate that.

What do you mean, what doesn't go as expected? The shift you specified should increase the date by one month and 6 days, isn't that what is happening? Can you show a before and after version of the metadata?
