Articles showing dummy date of 12/31/1969 in "Last Update" column

[tonycpsu]

Describe the bug
Since the most recent update, some of my articles are showing dummy date of 12/31/1969 in "Last Update" column.

To Reproduce
Not sure what caused it, but it seemed to appear around when I upgraded to Version 3.9.3 :fd467d52: (8375)

I use Inoreader as my feed backend, if that is relevant.

Screenshots

Please complete the following information:

• Vienna version: Version 3.9.3 :fd467d52: (8375)
• OS version: 14.1.1 (23B81)

Downgrading to 3.9.2 seems to fix this, FWIW.

Thank you, we thought we had made sure that no default date of 0 (milliseconds after 1.1.1970 00:00 UTC) can appear anywhere. Can you tell us the feed source as well? Then we can make sure that we refine the feature to avoid that behavior.
Can you add the column for creation date and see what that shows in cases when updated date is 0?

[tonycpsu]

Feed source is Inoreader -- it seems to affect all of my feeds, not a single RSS source.

Here's what it looks like with 3.9.3 release with published date visible.

Another anomaly here: Date published is later than last update
This is the Github feed for recent commits to vienna´s master branch (an atom feed)

I was not able to find the source of such anomalies. According to the current code, if the feed source does not contain the last update, it is set to the publication date if that exists, or to the date when the article was received. For the publication date, if the feed does not contain it, the updated date (if it exists) or the current date is used, whatever is earlier.

@barijaona, @josh64x2 or @Eitot, maybe you can find a reason for the observed anomalies.

I am not sure about my anomaly, it could have been caused by using a development version of Vienna. @tonycpsu did you use any beta version?
