[Bug 1872504] Re: date modified is wrong for files on an exfat formatted drive

[Sebastian Gürtler]

The fix is quite offtopic, but for this special case it should be a solution: the date of the pictures should be also preserved in the EXIF-Data. You can read the exif-data of the files and set the timestamp from this data.
I used another tool under windows for this so far, but exiftool should do the job:

Excerpt from the help-message:

exiftool "-FileModifyDate<DateTimeOriginal" dir
         Use the original date from the meta information to set the same
         file's filesystem modification date for all images in a directory.
         (Note that "-TagsFromFile @" is assumed if no other -TagsFromFile
         is specified when redirecting information as in this example.)

Hope that works,

Sebastian

Title:
  date modified is wrong for files on an exfat formatted drive

Status in ubuntu-meta package in Ubuntu:
  Confirmed

Bug description:
  When using exfat formatted drives (e.g. my camera card) with focal
  fossa any access causes the date modified to be set, even when it
  would not normally be set, and it is set a month into the future.

  Installing exfat-fuse and exfat-utils results in the correct
  behaviour.
