Feed is not being interpreted correctly

I’m adding this to my feeed
https://ieeexplore.ieee.org/rss/TOC4.XML
But I don’t think Newsblur is interpreting it correctly. I believe the problem is perhaps an error on the ieee webpage where the pubDate is too far in the past? Unfortunately I don’t see a chance of getting them to change this,…
thanks for the insight.

On rss.app it’s being interpreted correctly. NewsBlur manages to interpret it correctly but only for the last couple of months of items. As I said I think it’s a problem with the pub date.

I don’t know whether someone is “adjusting something”… but the link above now works…
HOwever, I see similar problems with similar TOC from IEEE, e.g.
