I just pulled a feed and checked it… Today is not the 30th of November! I’d think something has messed up the time/date settings somewhere. Double-check the WordPress time/date settings first and go back from there. But I think the validator choked on the format.
You might also look at the receiving site to see how they handle that. Do they schedule it for the 30th? Publish anyway? Or ignore the post? Or reject the whole feed?
Every feed reader or importer deals with errors differently… they are not required to adhere to standards.
When I saw the ‘last build date’ was munged I fed the feed to Heiko Behren’s Feed sanitizer but it didn’t change that date (I wasn’t really expecting it to do so) but there was another feed error and that was okay in the sanitized version.
You might try that sanitized feed in your system to see if it just rejected the format issue and the other problem W3 mentioned.

Yeah, the WordPress settings are showing the correct time and date, so I have no idea where this incorrect one is coming from.
It sounds like the site is just rejecting the feed completely. I don’t have visibility on the back end of that site, but when I sign into that site it shows dots scrolling above where the feed would be like it’s loading, but never moved beyond that point.
I don’t know if she’ll be happy with the sanitized feed as a temporary workaround, but I’ll pass it along. Thanks!
