Date missing in Arxiv feeds

gillesbonnet
I have started to use Zotero only recently, so please forgive me if my remark/question is stupid.

I have set up the following rss feed http://export.arxiv.org/api/query?search_query=cat:math.MG&start=0&max_results=99&sortBy=lastUpdatedDate&sortOrder=descending
Things work quite well, except that the date does not show up. Namely the date field is empty for each article.

Is there a reason for that? Or is it a bug?

    This would usually be because ArXiV isn't including that information in their RSS feeds. You will need to contact ArXiV about that.

    I see. It is weird because in other feed reader (e.g. Vienna) shows the date for exactly the same feed. I had a look at the XML file corresponding to the feed above.
    In an entry there are two items about time. The first is of the form
    < updated > 2017-10-16T15:40:31Z < /updated >
    while the second is of the form
    < published > 2016-03-03T19:39:34Z < /published >

    (Note that I added myself spaces around the symbols < and > since otherwise it would not appear in this forum)

    Shouldn't one of these two items be considered as the date?

    Another remark about this issue. Although the date does not appear when it is in the RSS feed, it does appear correctly when it is added to my library.

    You mean when you click the Add to My Library buttions in the feed?
  • gillesbonnet
    Yes.
    1. I click the "Add to my Library" button in the feed
    2. I go to My Library and click on the corresponding article
    3. the date appear (and is correct) in the information column on the right

    This is a good thing. I mentioned that because I am surprised that once it is in my library the date is well retrieved, but when it is in the feed there is no date appearing.

    Hmm, that does seem like a potential bug in the display of the feed items then.

    Date parsing was broken for Atom feeds. I've fixed this for the next version — thanks. As noted, this doesn't affect saved items, only the ones displayed in the feed.

    Wonderfull! It now works fine for me. Thanks.
