I'd rather use the stable (yes, I know that it's beta) versions as
this is the wifey machine and I don't need any unforeseen problems or
surprises. Thanks for the suggestion, though.

Like i cannot reproduce this problem on my computer with you rpicture sample, we need to investiguate better.

Question : can you give me the root album library path where are stored your pictures. Are you used a network shared path ?

Interesting. I don't know where to go from here. I can try to build
from SVN, but that will be in a few days.

Hello,

Just to make it a bit clearer for me (and maybe others) :
If I'm not wrong, there are a few dates associated with a picture :

1) in file properties :
- time of last access (not very useful for us)
- time of last change in the data of the file
- time of last modification of the file status
(ususally, change and modification date are the same)

This is common to any file on a unix file system.

2) in EXIF :

at least
- DateTime
- DateTimeOriginal
- DateTimeDigitized
And also some fields in IPTC.


Could you configure digiKam to display in tooltip "camera date" and
"file date" ?
And also, configure digiKam (Album settings) to display "file creating
date" and "file modification date"

Then, give us the 2 dates you get...

These are the _File_ date properties on file system. This is not the date when have be taken the picture.
 

2) in EXIF :

at least
- DateTime
- DateTimeOriginal
- DateTimeDigitized
And also some fields in IPTC.

There are the date when have been taken the picture. this date is used by digiKam to perform search.

Could you configure digiKam to display in tooltip "camera date" and
"file date" ?

It's already in Photograph properties every where.
 

And also, configure digiKam (Album settings) to display "file creating
date" and "file modification date"

Already exist in Setup Album page

Thanks, I'm at the university right now but when I get home I'll set
it up to display the needed info in the tooltips. I thought that I
turned on all the available dates in the tooltips, but I may have
missed one or three.

Fabien, in the meantime I'll forward to you a screenshot that I sent to Gilles.

Thanks.

Dotan,

You can check into you sqlite database file if image date stamp are correct. The file is digikam3.db stored in you root album library path.

i use 'sqlitebrowser' program to display content. others DB GUI don't work properlly (kexi, knoda, etc.)

http://sqlitebrowser.sourceforge.net/

The file content have some tables easy to understand.

If you don't understand DB stuff, you can send this file by private mail.

Hi,

Dotan, I received your screenshot.
There's one thing that is unclear :
- we can see that the photograph properties are correct, showing the
right creation date, in the tooltip and in the sidebar (2 different
pictures)
- we can see other pictures in the main thumbnail view which have the
same date for creation and modification

Does this apply to all your pictures, ie creation date showed under the
thumbnail doesn't match the creation date you see in the photograph
properties ?

If it's the case, that would be the problem. I guess this is why Gilles
asked you the database to check it...

Well, just to check if Date recorded in database is right....

Sorry for the delay. I'll check the DB tomorrow when I get home. In
any case, exiv2 0.14 has been released today, so I'll install that as
well and report back. Thanks!

Alright, I think that I've identified the problem. The database has
the wrong dates for some reason. I simply copied the database from my
old 0.9.0 installation. But when I copy and reimport a photo, then it
has the correct date.

I would simple erase the digikam.db file, but then I would lose all my
tag information. Is there a way to either:
1) Have the database rebuild the date information?
    or
2) Save the tag information so that I can reimport the photos?

Thanks in advance.

With the sqlite3 tool, execute
"UPDATE Images SET datetime=null;"
Then at startup, scanlib should update the date information.
Of course make a backup of your database file!

Thank you, that worked fine. Upon startup Digikam rebuilt the missing
info and now the dates are correct.
