[digiKam-users] Adjust date for scanned photos with unknown or partial known date (and time)

[Henrik Hemrin]

Thanks Paul for your suggestion,

It can be a method. 

Your answer indicates it may not work to adjust date in digiKam as I want to (and could in PSE). 
If I need to use a work around, beside your suggestion, I consider to use a fictive date, eg 1 Jan 1800 for photos with unknown date, in combo with a tag with as many date details I know for each photo. 

I still hope someone can tell me there is a proper method in digiKam.

Best regards
Henrik

The answer from Paul Kean did not for unknown reason arrive in my e-mail, so I paste from the arcihive: 

 Hi Henrik
I got around this problem by embedding the date in the filename and then sorting by filename. That way you can make up you own rules about handling of unknown dates.
