 * I’m looking for an answer similar to this. When I submit the sitemap to google
   webmaster tools, an error message returns stating:
    “An invalid date was found.
   Please fix the date or formatting before resubmitting.” And an example is displayed:
   Parent tag: url Tag: lastmod Value: -0001-11-30T00:00:00+00:00
 * How is this overcome?

 * I’ve verified that I’m using the most recent version and I seem to have things
   configured correctly. I guess the bottom line is this: In Google Webmaster Tools,
   the sitemaps are successfully submitted even though it lists the error of invalid
   date. How (if at all) does this affect my site;s SEO? Is a fix or a work-around
   even necessary?

 * I’m having the same issue. Is there any fix for this yet? I’m running the latest
   version, 1.4.7.
