EXIF data

[rich]

I upload my photos to windows 11.
I am using GIMP 2.10.38


I like to order my photos by date/time taken but on a recent holiday my phone automatically changed to the local time but I forgot to change my camera so now some of my photos have an hours difference in time. 

Is there any way within Gimp to change the 'time taken' field to add an hour to make them align to the phone camera photos? I've looked at the metadata editor but it doesn't seem to include this field.
I could do it in windows photo editor but it seems you can only do it one at a time and would therefore be a lengthy process, whereas I am alread checking them in Gimp.


Thanks

I can not recall any batch plugin for Gimp although Ofnuts does have a plugin that opens each file for editing in turn (I think) ofn-save-next.py from https://sourceforge.net/projects/gimp-to...s/scripts/

A non-Gimp alternative might be XnViewMP https://newsgroup.xnview.com/viewtopic.php?f=82&t=47966

Where you can edit the metadata (1) for selected files (2) changing time (3) and applying to all selected (4). You can also check the existing before / after selection (5)

Using Gimp for this is complete overkill, you can do this with a single call to the exiftool utility:

exiftool "-AllDates+=01:00:00" -verbose *.jpg

• You would use -= instead of += to go back of course
  
• You can remove -verbose when you are confident
  
• You can add -overwrite_original before the filename(s) when you are confident (otherwise ExifTool we keep the original files around)
  
• I understand that there is a GUI version (ExifToolGui) for the meek :-)
