epub date error fails epubcheck 1.05
I used pages to convert a book to epub. It works and passes the epubcheck but I need to put a custom cover without borders (which Pages cant do)
So I open the epub file in Calibre, add a custom book cover image and export out to epub again. The custom cover works fine.
But when I do an epubcheck I get the error:
epub/content.opf:date value '2009-12-28T08:00:00+00:00' is not valid,
YYYY[-MM[-DD]] expected.
I can unzip the epub file and read the OPF file, but I don't know what to change the date to to correct the problem.
Any ideas?
