Hi, I have the same invalid date problem through the SEO plugin by Yoast. Where you able to fix it? If so, kindly explain how. Thanks.
Was a solution found for this issue? One of my site has 27 sitemaps, 15 of which have the -001-11-30 00:00 last modified date.
WordPress: 3.5.1
Yoast SEO: 1.4.7
Using the sitemap plugin from http://ww.wp.xz.cn/extend/plugins/google-sitemap-generator/ and disabling the Yoast sitemap generator was the only viable stop-gap measure that worked for me.
I deleted the main sitemap_index.xml from webmaster tools and submitted all of the individual sub sitemaps. The sub sitemaps returned no errors. It will do until a solution is found.
^^ thnx for the info. Hopefully a simplier solution will be found soon
A lot of discussion on this today. Can this be a result of wordpress 3.5.2?
Possible, I believe I’ve found the offending issue with my sitemap.
The category timestamp is different than the others
<sitemap>
<loc>http://www.coralseait.com/attachment-sitemap.xml</loc>
<lastmod>2013-06-22T00:58:11+00:00</lastmod>
</sitemap>
<sitemap>
<loc>http://www.coralseait.com/category-sitemap.xml</loc>
<lastmod>2013-06-23 13:04:02</lastmod>
</sitemap>
<sitemap>
Notice the different format, and this is indeed the line google complains about. I tried updating a category to force a new timestamp which did happen, but still in the wrong format.
^^ yea saw that. Not sure how to modify code to fix tho
Not a good thing, I like Yoast’s Sitemap generator. I use 3.5.2 and the previous version of Yoast SEO, and it works great, that’s my solution :-). The old one ain’t broke.
I’ll only upgrade to the latest Yoast once this issue is fixed, and something about titles I saw in another post …
^^ which version you using? The previous one seems like, the XML map is broken.
I use 1.4.7, perfect sitemap, well-indexed by Google, no errors at all. Same with Bing.

It appears 1.4.10 contains a few changes in xml-sitemaps.php
Since these changes, the sitemap will be generated with an incorrect date format.
I have the same issue and hopefully the dev will fix it soon.
Take a look at : http://plugins.trac.ww.wp.xz.cn/changeset/729601/wordpress-seo/trunk/admin/pages/xml-sitemaps.php?old=729023&old_path=wordpress-seo%2Ftrunk%2Fadmin%2Fpages%2Fxml-sitemaps.php
Without knowing much about php, I think I have managed to narrow down the problem to date format with custom taxonomies.
To sort out the issue (which worked for me), the following lines should be edited in wordpress-seo/inc/class-sitemaps.php file:
Line 249 and 250, which currently read:
if ( $query->have_posts() )
$date = $query->posts[0]->post_modified_gmt;
Should be changed to:
if ( $query->have_posts() ) {
$date = $query->posts[0]->post_modified_gmt;
$date = date( 'c', strtotime( $date ));
}
This puts the date in correct format. As I said, it worked for me.
Bare in mind that I am not a programmer, but just a man with a lot of persistence. I’m not sure how the above edit affects the rest of the file – it shouldn’t affect it adversely.
Good luck!

The sitemaps at the lower level, like “…/page-sitemap.xml” have no faults. The top level one “…/sitemap_index.xml” has a problem with an invalid data.
In Dutch (i’m sorry guys) the index error is:
Bovenliggende tag: sitemap
Tag: lastmod
Waarde: 2013-06-23 17:43:46
I have a new site, so indexing should hopefully happen for me. If not it’s probably because of this index error.
Hope it is solved soon. I love the plugin.
