Problem

In the latest Smoothie POC (openfoodfacts/smooth-app#4674), we want to display an additional icon for pictures that are outdated - let's say more than 1 year old.

There are two problems.

First, we expect seconds in images_to_update_fr. But looking at https://world.openfoodfacts.org/api/v3/product/3017620422003?fields=code,product_name,images_to_update_fr, we get

• "front_fr":91593030 (1060 days)
• "ingredients_fr":200038598 (2315 days)

Which does not match what we find in history about last modification for https://fr.openfoodfacts.org/produit/3017620422003/nutella-ferrero:

• 2023/08/24-06:31:01 CEST for "front_fr"
• 2023/08/14-13:53:56 CEST for "ingredients_fr"

Is there something wrong? (possibly, my interpretation of how to read the data)

Second, AFAIK we get the image freshness only for the specified languages.
And we would like the image freshness for all languages, a bit like what we have for product name ("product_name_languages").
A typical use case would be: "I query the data in French, but I would like an access to all languages' image freshness data, so that in my image screen I can display the freshness of images not only for French images but Italian images".
Something like 'image_to_update_languages'?

Proposed solution

1. check the exact meaning of the int values of 'image_to_update_xx'.
2. implement 'image_to_update_languages' or specify the already existing field.
