Manage epoch date format

[dariopnc]

Hello everyone: I have this drone (DJI) that saved pictures and videos without properly setting date/time tags, but appends the shooting date in epoch format (seconds from 1/1/1970) to the filename.

e.g. DJI_export_1656844941.jpg (for Sun, 03 Jul 2022 10:42:21 GMT)

I haven't been able to use that to add the shooting date into the tags. I also searched the website and the forum with no luck.

In case I missed some important info, can you please ponit me to it? Otherwise can this be a new feature?

Thank you for the great job so far, btw!

You have to strip away everything from the filename other than the timestamp numbers and then use the -d (-dateFormat) option with %s as the format (see Common Date Format Codes for full list of codes).

Example:

Code Select Expand

C:\>exiftool -P -overwrite_original -d %s "-AllDates<${Filename;m/(\d{10})/;$_=$1}" Y:\!temp\ccc\a\DJI_export_1656844941.jpg
    1 image files updated

C:\>exiftool -time:all --system:all -G -a -s Y:\!temp\ccc\a\DJI_export_1656844941.jpg
[EXIF]          ModifyDate                      : 2022:07:03 10:42:21
[EXIF]          DateTimeOriginal                : 2022:07:03 10:42:21
[EXIF]          CreateDate                      : 2022:07:03 10:42:21
