Just built site two month(Y2015), but cache date of some pages is 2012

Dear All,

Just built site two months(Y2015), but cache date of some pages is 2012

Found that because we use Joomla CMS template, google thought those pages were our site, the cache date is 2012.

We already disable those pages, now it is 404.

We did above over one month already, but google still show those pages in 2012 if we use site:domain.com to check in google.

Can I put my real domain name here?

Thanks,

I would do a archive search for the domain looks like it was a website in 2012 and you will need to (as best you can) find all the old pages and 410 them.
The cache will update to the new date but you might have old links pointing to old pages you might want to find.

You can use webmaster tools to ask for these pages to be removed from the index.
I doubt if the problem is anything to do with joomla, but rather to do with buying an old domain.
