Properties view: wrong creation date

[Jan Wolter]

Hello,

I mentioned that the creation date of nearly all my raw files are not 
displayed correctly in the photograph properties view: the date part is 
correct but the time part is fixed to "1:00 AM" or "2:00 AM" depending 
on winter or sommer time. For read-only files like raw files my digikam 
writes/reads all metadate to/from XMP sidecar files. Currently, I use 
digikam version 5.7.0 (AppImage).

When I take a look in the *.xmp files, I see the following entries 
related to dates:
exif:DateTimeDigitized="2014-07-29T11:22:08"
exif:DateTimeOriginal="2014-07-29T11:22:08"
tiff:DateTime="2014-07-29T11:22:08"
xmp:CreateDate="2014-07-29T11:22:08"
xmp:MetadataDate="2014-07-29T11:22:08"
xmp:ModifyDate="2014-07-29T11:22:08"
photoshop:DateCreated="2014-07-29"

All date related attributes except "photoshop:DateCreated" saves the 
date including the time part. First question: Why is there a photoshop 
related attribute? I use dk on a Linux machine, where Photoshop is not 
present.

In a deeper investigation of the problem, I noticed that the mentioned 
problem applies only to all raw files which XMP sidecar files was 
created by an older dk version (in my case dk 4.14.0). All "new" raw 
files which sidecar files was created with digikam 5.x are displayed 
correctly and the attribute "photoshop:DateCreated" includes the time 
part. When I take then such a xmp file and change the attribute from
   photoshop:DateCreated="2017-11-04T12:52:23"
to
   photoshop:DateCreated="2017-11-04"
the properties view shows "11/4/17 1:00 AM" instead of "11/4/17 12:52 PM".

It seems to be that digikam uses the attribute "photoshop:DateCreated" 
exclusively instead of "xmp:CreateDate". From my point of view thats a 
bug. Is it possible to fix it?


Best regards,
Jan
