Hello..
Can anyone tell me how to convert the FileDateTime to a human readable date?

$conf['show_exif_fields'] = array(
  'FileDateTime',
  );

This is how it currently reads under the picture on the picture page

FileDateTime    1441306325

It seems I don't have too much information in my metadata on my images. I don't know why my Nikon  P520 doesn't put more info in the metadata.
So I need to have this converted so I can at least have a date for the image.

Thank you,
Scott
