Show Created Date in a result of search center

One of my customers asked me to put created date instead of modified. The solution which I wrote below , maybe is not beautiful, but it works.

First of all, I needed to map managed property in the Central Administration:

Search Service Application -> Metadata Property Mappings :

"New managed property" , for me it was ''CreatedDate" and I needed to map it.

I found some answer in the internet : Article ,

but in my situation it returned 1/1/1601. Therefore , mapped all of the fields from the article separately. So, for me it was Basic:15 - the right result. But for everyone it differences.

And, of course, after do it, I had to run full crawl.

When I did all these things, I needed to edit the search results web part :

1.Insert to "Fetched Properties" new Column "CreatedDate"

2.Insert to the "XSL Editor" new template for CreatedDate

It's all for this time.
