Change Create date to scanned files using only year?

[abunavas]

Hi,
I have a bunch of scanned jpg files. EXIF info is something like this:

Code Select Expand

File Modification Date/Time     : 2021:05:17 19:22:41+02:00
File Access Date/Time           : 2021:05:18 19:03:00+02:00
File Creation Date/Time         : 2021:05:17 19:22:41+02:00
File Permissions                : -rw-rw-rw-
File Type                       : JPEG
File Type Extension             : jpg
MIME Type                       : image/jpeg
JFIF Version                    : 1.01
Resolution Unit                 : inches
X Resolution                    : 300
Y Resolution                    : 300
Exif Byte Order                 : Little-endian (Intel, II)
Make                            : HP
Camera Model Name               : LaserJet MFP M129-M134
Page Name                       : Reflective
Software                        : VueScan 9 x64 (9.7.27)
Create Date                     : 2021:05:17 19:22:41

I wish to chage Create Date to year only. For example, this particular photo is taken in 1975. I don't care for month, day or hour. Is it possible and how, please?

Im not think $Exif:CreateDate will grant lonely years, but you could use zeroes for everything else like...
-Exif:CreateDate="1975:00:00 00:00:00"

Thank you.
I received error


Warning: Month '00' out of range 1..12 in ExifIFD:CreateDate (PrintConvInv)
Nothing to do.


I'll just use 01 for month and day

See FAQ #5 for details on setting date/time tags.

I received the error

It must be better filtering from new updates, because v12.11 even grants -Exif:CreateDate="0000:00:00 00:00:00"

From Version 12.14
     Patched to issue warning and avoid writing date/time values with a zero month or day number

As I faintly recall, the 00 caused issues with something else.

You can override this by using the -m (-ignoreMinorErrors) option and set it to whatever you want, even the number of monkeys in the picture.

But the standard I've seen with images from stock image sites like GettyImages is to put the earliest date/time when it is not known.  So if only the year is known, GI would put 1975:01:01 00:00:00

Of course when seeing this, I had to experiment with  exiftool -n -Exif:CreateDate="xyz" file.jpg
Lol, and sure enough my date was xyz! But I do certainly agree, its always best to follow the standards.
