"Files" module: how can I display Author & Date?

In the file view_unit.html we can point all useful for users information that will be displayed at every page with published file. 

But how can I display in view_unit.html  Author (Name and Surname) and Date of media?

About date:

In BxFilesPageView.php I wrote this string:

'fileDate' => getLocaleDate($aFileInfo['medDate'], BX_DOL_LOCALE_DATE_SHORT),

In view_unit.html I used this command:

__fileDate__

But I always get date 01.01.1970 .

Why??....

Correct line of code would be:

'fileDate' => getLocaleDate($this->aFileInfo['medDate'], BX_DOL_LOCALE_DATE_SHORT),

Thank you very much. Now it works properly.

May be you have some advices about "Author" field, AlexT? ))
