feed pubdate

As far as I can see, WP feeds use UTC, not the feed source’s local time. The times are the same as the pubdate you see on the post itself if you apply the timezone offset.

I know, but using dlvr.it to publish on a facebook group, sometimes the time is too remote and I believe it publishes the article

That would seem to be a facebook issue.

maybe a dlvrit.com issue (not FB)

Perhaps. Check with their tech support.
