[Plugin: Google XML Sitemap for Videos] Date Error on Webmaster Tools

The Syntax seems to be perfectly right.

I removed the publication_date line from the file – it is optional – and google webmasters shows no more errors.

I redownloaded the plugin, reinstalled, deleted the old xml, let it parse again Video Site Map

Webmasters instantly shows the same errors again as above.

I haven’t found further infromation to this, as stated above teh syntax looks correct, you can take a look yourself here.

Webmaster Tools say:

Line 15: Invalid date – An invalid date was found. Please fix the date or formatting before resubmitting.

Parent tag: video
Tag: publication_date
Value: 2010-08-24T03:50:44+0000
Problem detected on: Aug 25, 2010

and on further date lines furhter below.

Noone has an idea if that is an error caused by the plugin or a display parsing error at google webmasters tools?

Thanks

Today Webmaster tools stopped showing errors, even though I did not change anything the past days.
this resolves the ticket and answer the question from the last post, too. Just a bit sad that even though the Author responded to other threads during the past weeks, he ignored this one.
