Hey there,
EasyBlog uses the date format that is defined in Joomla's /language/en-GB/en-GB.ini and the string is "DATE_FORMAT_LC". I believe it doesn't generate the date in seconds. If you need it to be in seconds, I believe it should be DATE_FORMAT_LC2 . You can edit the file /components/com_easyblog/themes/wireframe/blogs/latest/default.main.php and at line 116, replace the codes below,
DATE_FORMAT_LC1
With,
DATE_FORMAT_LC2
But it's strange that you need it to be displayed in seconds though?
