This might be a bug then and it is better to submit it on bugs.kde.org

    When I run exiv2 on raw files where the sidecar file was created
    with dk 4.14 I get the following output:

    
    $ exiv2 -pa --grep Date 2014-08-04T15-41-27_Australien.ORF

    In the first case Xmp.photoshop.DateCreated does not contain the
    time information and digikam shows the property "Created" as
    "8/4/2014 2:00 AM". Surprisingly, the old dk version 4.14 shows the
    creation date correctly, even if the attribute
    Xmp.photoshop.DateCreated contains no time part.

    It seems to be that there are some changes from versions 4.x to 5.x.

      It might be related to how exiv2 supports the ODF file
        format.
      It should be easy to check. You can try either exiv2 direct
        or darktable, RPD and many others and see if they read the
        date/time tag correct.

      I noticed the same problem with pre-released version 5.8.0.
      Absolutely 

      annoying is that renaming of a set of images (all taken on the
      same day 

      but on a different time) with the option
      [date:"yyyy-MM-ddThh-mm-ss"] 

      results in

      2014-07-29T02-00-00.ORF

      2014-07-29T02-00-00_1.ORF

      2014-07-29T02-00-00_2.ORF

      ...

      2014-07-29T02-00-00_n.ORF

      
      I would expect a filename including the correct time information
      taken 

      from the xmp:CreateDate attribute. But it seems to be that always
      in 

      incomplete attribute photoshop:DateCreated is taken.

      
      Does anyone have the same problem?
