When I compare a file that uploads correctly (into Mapillary) and a jpg file that fails in EXIFTOOLS I see that it doesn't have Create Date, Date/Time Original and Modify Date. There are lots of other fields as well but these are the only ones dealing with time.

enter image description here

When I try to use 

'.\exiftool(-k).exe' -"Date/Time Original"="2019:10:27 18:14:10.5" Photo_2019_Jul_12_13_38_40_019.jpg

It doesn't let me add the tag (I assume) because it has a '/' in it. It also doesn't allow "Create Date" for example. enter image description here

How can I create a tag with these?

  • did you get an error message of any kind? On what do you base that assumption? – erik258 Oct 30 '19 at 00:28
  • Sorry I forgot to add that - I get `.\exiftool.exe -"Date/Time Original"="2019:10:27 18:14:10.5" Photo_2019_Jul_12_13_38_40_019.jpg Warning: Invalid tag name 'Date/Time' Nothing to do.

See ExifTool FAQ #2

"Date/Time Original" isn't the tag name, it's the tag description, which can change depending upon the set language (see the -lang option). Tag names don't have spaces or special characters. The actual tag name to set a value is DateTimeOriginal.

So your command should be
.\exiftool(-k).exe -DateTimeOriginal="2019:10:27 18:14:10.5" Photo_2019_Jul_12_13_38_40_019.jpg

Though take note that DateTimeOriginal doesn't hold a subsecond value. The location for that would be SubSecTimeOriginal. But exiftool does have a shortcut. If you set SubSecDateTimeOriginal, it will set the DateTimeOriginal and SubSecTimeOriginal tags. Also, if you add a time zone to the end of that, it will set OffsetTimeOriginal, where the time zone value is held.

For example:
.\exiftool(-k).exe -SubSecDateTimeOriginal="2019:10:27 18:14:10.5-04:00" Photo_2019_Jul_12_13_38_40_019.jpg

  • Thanks.,.using SubSecTimeOriginal worked. Now I have to figure out how to run this as batch to read the `=.\exiftool.exe -FileCreateDate Photo_*jpg` and use this to then run `.\exiftool.exe -SubSecDateTimeOriginal="" Photo_*.jpg` – GeorgeC Oct 30 '19 at 02:04

    No need for scripting, use this command. It will process all files in the directory. Add `-r` to recurse into subdirectories. You'll find it much faster than scripting a loop (see [ExifTool Common Mistake #3](https://sno.phy.queensu.ca/~phil/exiftool/mistakes.html#M3)) `exiftool "-SubSecDateTimeOriginal – StarGeek Oct 30 '19 at 02:35
