I’m using publii with tattoo theme (and some overrides).
It seems that dates are wrong in feed.xml and feed.json.
The site last update date is always “1970-01-01T01:00:00+01:00”.
The modified and created dates are the same for all blog posts, most probably the date of last website sync.
My website : https://www.sylvainmoingeon.fr
Link to feed validator : https://validator.w3.org/feed/check.cgi?url=https%3A%2F%2Fwww.sylvainmoingeon.fr%2Ffeed.xml
You’re right – there is a bug here. I have created an issue on Github: https://github.com/GetPublii/Publii/issues/785
