Date/Time and EXIF-Data?

Hello together,

I don't quite understand the way Digikam handles the dates and times of the
pictures (as of Beta2):

There seems to be no way to change the EXIF-provided date and time. I can,
however change the date and the time with the side bar or the menu entry.
This does unfortunately not change the EXIF-values, only Digikam's database,
so bringing EXIF and DB out of sync. Is this by design? I hope not....

Moreover, can't EXIF-Tags be created for pictures for which the camera (e.g.
my mobile phone) does not create any? I'd like to have as many values as
possible stored within the picture, re-usable for other software.

Anders

Which values are written to the metadata can be configured in the "Metadata"
tab of the settings. Have you toggled on the "Save image time stamp..."
option at the bottom?

Yes, that should be turned on. At least in the GUI it is.

The corresponding entries in the config file read:

[EXIF Settings]
EXIF Rotate=true
EXIF Set Orientation=true
Save EXIF Comments=true

And in another place of the config file (???):

[Metadata Settings]
IPTC Author=
IPTC Author Title=
IPTC Copyright=
IPTC Credit=
IPTC Source=
Save Date Time=true
Save EXIF Comments=true
Save IPTC Credits=false
Save IPTC Photographer ID=false
Save IPTC Rating=true
Save IPTC Tags=true
