Hi!

Yesterday I noticed that the modified time on photos copied to my computer from a memory card was two hours off. I checked photos copied to the computer before I upgraded to Mint 18 and there the time is correct. I had a search on Google and I think the bottom line is some bug (not in Mint itself) which makes the system assume that timestamps is in UTC on the fat-formatted card and thus compensating for that to CEST.
I found this "solution":
https://forums.linuxmint.com/viewtopic.php?t=234372
But this feels more like a workaround than a solution and when I entered the suggested command (timedatectl set-local-rtc 1) I got a warning that having the the system clock at local time wasn't fully supported (or something of that sort), so I reverted to the original setting.
I later found this workaround on some site that mounts cards with a time offset: This works, but is a bit of a pain, since I have to unmount the card first.
So, I have three questions.

1. Is there a hope for an update that will fix this issue?

2. What would be the best solution/workaround in the meantime?

3. Since I have rather a few photos that I've copied to the computer before I discovered the problem I have an idea of writing a script that reads the time/date in the EXIF-info of all the files in a folder and then updates the file times/dates with touch. But I think I need some tool to read the EXIF-info and my knowledge of scripting in Linux is close to zero. So I hope maybe someone could help me in the right direction

Thank you!

Regarding #3, exiftool should do the trick e.g. to adjust the EXIF timestamp forward two hours for all jpg files in the directory:

I wish I had seen something like that back when I had hundreds of photos off by one year.

If what you are trying to do is set the file system time stamp to match the EXIF data, then you'll want a recipe more like this:

There's more recipes at the exiftool page. Or in the manual page for exiftool itself.

Wow, I'll look into that! If it's that easy I won't even need a script I just had a quick look on the exiftool page and it seems I can also update the dates in the exif-info just as easy, which could come in handy as I almost always forgets to set the camera to the correct time for a few weeks when time changes to and from daylight saving time.

Will this work with CR2 (Canon RAW-files) as well? And also, if I would update the date/time in the exif-info in a file with this tool, would that file be identical to one coming straight out of the camera apart from the date/time, i.e. would everything else be untouched?

Never mind the question about CR2 support, just saw that it was in the supported file list on the exiftool page.

It should do. Check out the Supported File Types section at http://www.sno.phy.queensu.ca/~phil/exiftool/ .

As far as I know, exiftool doesn't change anything apart from what you explicitly tell it to. You can confirm this by running exiftool with no parameters on an original image to obtain information on it, and then redoing that on the converted file, comparing both outputs with something like diff (command line) or meld (GUI).
