Wrong dates added for non-English locales

[VojtechDostal]

I uploaded a few pictures a few days ago using the latest version of the app. An automatic category to sort the pictures by date was added to each of them, which is cool, but the category does not exist:

See eg:

Also the app thinks I uploaded them on 10th August 2020 rather then 2019... could that be a problem with my phone, though?

Hmm, I've just tested the alpha and found no issue with the date taken - https://commons.wikimedia.org/wiki/File:San_Gimignano_2.jpg . The hidden category https://commons.wikimedia.org/wiki/Category:Photographs_taken_on_2019-07-05 does exist for me - I suspect the reason it doesn't exist for you is because the date is in 2020. :)

Is anyone else able to reproduce this? Vojtech does your phone display the current date correctly to you (aside from this app)?

Do we really need this date category?
Maybe the bug is that the date format varies with the locale?

I don't think the category was made by us, it seems to be added to Upload Wizard uploads too, i.e. https://commons.wikimedia.org/wiki/File:Kirkkokatu_27_Raahe_20190705.jpg

Then the easiest is probably to create a Phabricator ticket and forget about it :-)

I don't think the problem is with the category creation though... it seems to be a side effect of the wrong upload date. It makes sense for uploads made "in the future" to not have the category created yet.

A few examples found:

• Photographs taken on 10. 08. 20 (Czech locale)
• Photographs taken on 27/08/2019 (Nepali locale)
• Photographs taken on 2019-07-05 (English locale) ← Only this one is valid

So, instead of writing the date using the user's locale, we should code it explicitly as year + "-" + month + "-" + day.

@nicolas-raoul , is this the same issue as the one reported in our public forum? If so (and the dates are indeed wrong for all non-English locales), we should prioritize this fix since it's a big problem.

Wrong dates appear in the files description pages due to the application

@misaochan Yes, I am pretty sure it is, and I share your view that it is a priority issue, because it forces Commons people to fix our mess, giving the app a bad reputation.
