Title: Date modification
Post by: macfun on April 02, 2020, 05:26:53 PM
Hi everyone

I'm a new user of exiftool, everything was going very well until now, because I'm struggling a bit for one thing...
During my last holidays I used my old gopro, and the date was set on 2013... I just want to change the date to the real date of the picture because I use synology moments and my pictures are sorted by date.

So, I tried  exiftool '-alldates=yyyy:mm:dd hh:mm:ss' but it doesn't fully work... It changes some of the dates, but not all of them... I want to have the date 2019:08:03

If I use exiftool -time:all -a -G0:1 -s, here are the results before -alldates
[File:System]   FileModifyDate                  : 2013:01:01 00:16:42+01:00
[File:System]   FileAccessDate                  : 2020:04:02 23:03:04+02:00
[File:System]   FileInodeChangeDate             : 2020:04:02 23:03:03+02:00
[EXIF:IFD0]     ModifyDate                      : 2013:01:01 00:16:42
[EXIF:ExifIFD]  DateTimeOriginal                : 2013:01:01 00:16:42
[EXIF:ExifIFD]  CreateDate                      : 2013:01:01 00:16:42


here are the results after :
[File:System]   FileModifyDate                  : 2020:04:02 23:19:53+02:00
[File:System]   FileAccessDate                  : 2020:04:02 23:20:07+02:00
[File:System]   FileInodeChangeDate             : 2020:04:02 23:19:53+02:00
[EXIF:IFD0]     ModifyDate                      : 2019:08:03 15:30:00
[EXIF:ExifIFD]  DateTimeOriginal                : 2019:08:03 15:30:00
[EXIF:ExifIFD]  CreateDate                      : 2019:08:03 15:30:00


Moreover, if I do a cmd+I with my mac, the results are :
creation : 2020:04:02 23:19:53
modification : 2020:04:02 23:19:53

I had différents errors, the last one is Warning: [minor] Unrecognized MakerNotes

Do you have any solution to change all the dates to the one I like ?

Many thanks !! :)

Try this:

exiftool "-time:all=2019:08:03 15:30:00" -wm w DIR

This should change all writable date/time tags except =the filesystem ones.

Hi Phil,

Thanks for all your amazing job with ExifTool and for your reply !

Unfortunately, I think it's not working, I've got an error message : Warning: [minor] Maker notes could not be parsed - and it has set the EXIF dates as wanted but not the system dates ... :
[File:System]   FileModifyDate                  : 2020:04:03 08:38:02+02:00
[File:System]   FileAccessDate                  : 2020:04:03 08:38:03+02:00
[File:System]   FileInodeChangeDate             : 2020:04:03 08:38:02+02:00
[EXIF:IFD0]     ModifyDate                      : 2019:08:03 15:30:00
[EXIF:ExifIFD]  DateTimeOriginal                : 2019:08:03 15:30:00
[EXIF:ExifIFD]  CreateDate                      : 2019:08:03 15:30:00


Maybe it's because it's a GoPro picture ? ::)

That's just a warning.  As long as the other data is changed, then you can ignore it.

Add -FileModifyDate='2019:08:03 15:30:00' to fix that.

Also, since you mentioned it's on Synology, it has been reported here that the "Drive" package will prevent any attempts to change the file system dates.

Ok, thanks, I'll just ignore it !

Sorry about that, I've read to quickly... Quarantine + short night effet probably  ::)

It worked, thanks ! Not at the first time but I did it twice and it worked... I've got a lot of pictures to edit, hope everything we'll be fine !

Actually the photos I'm trying to edit are still on my computer hard drive. I'll transfer them on the synology when they'll be ready  ;D

Thanks again :-)
