I think I found the relevant thread, but there was only this
suggestion:

,----
| read pictures exiv for datestamp
| crop it to digits only
| (remove dot)
| black and white
| gorc
| -> database
`----

But this is already what I do - only that in my case gocr does not
recognize the digits and that I would like to keep the decimal point.
Unfortunately your sample picture wasn't online anymore, so I couldn't
compare it to my data.


Best,
