I know, I know, the Calibre date is more precise. However, this is stopping me from publishing ePubs to the Apple iBookstore. I opened my ePub files in Sigil and tried to find and alter a line, but to no avail. I'm not a programmer, I'm a writer and publisher.
What can I do to get the correct line of code, that is, the DATE, into epubcheck 1.0.5 desired state?

And after you manually change it, ask the epubcheck authors why they are invalidating a valid date that complies with EPUB standards. The problem is in epubcheck, not Calibre. It's not that Calibre's date is more precise, it's that Calibre's date format complies with EPUB standards.
