Description .nedberg 2007-05-27 17:53:13 UTC
Version:           0.9.1 (using KDE KDE 3.5.6)
Installed from:    Ubuntu Packages

When I import images from my Canon IXUS 850IS using the add-date-and-time function in the camere view, the images get the wrong name. A picture taken at 19:22:25 (HH:MM:SS) will get the filename 20:22:25. I have tried changing the timezone on my camera and setting daylight saving both on and off. I even changed the timezone on my computer, but nothing helped. The only thing I could do was to use incorrect time on my camera. The EXIF information is correct, but digiKam will not use the correct time.

Nedberg,

Can you give me a picture sample from your camera to test with the right date where have been taken the image. Thanks in advance

Hi, thank you for looking into this!

The attached image was taken today (2007-08-25) at 17.21 GMT+1. The
EXIF-time is correct, but if I download it with digiKam it will use
18.21 as the time. I tried to look into this myself and found that
digiKam uses the modification time of the file. I do not know why my
camera gives the image a modification time of 18.21, but digiKam
should use the EXIF time anyway.

Hope you find the time to fix this for me!

Even Nedberg

Nedberg,

Ok, now i understand where is the problem. Thanks for this investiguation. Using the Exif date is a possibility to study.

Like your camera is a Canon one, i suspect than you use the Gphoto2 driver to download images to computer. Look into Help/Camera Info dialog for details.

digiKam use the Gphoto2 to handle files from camera like a virtual folder. Date & time of files are given by Gphoto2 driver. It's possible than driver has a bug...

If you can use a Flash Card reader, mount your camera memory device like an USB MAss Storage media. This on e do not use Gphoto2. If the date the right when you download, the bug is in GPhoto2 drivers, else this is a problem with your camera. 

Note : the code to interface Gphoto2 drivers or the UMS digiKam drivers is the same. This is why we can compare results as well.

Nedberg,

Look this entry: http://bugs.kde.org/show_bug.cgi?id=147986

It's sound like a similar problem with Canon Camera...

You were right! When I used a USB card reader the image time was
correct. I hope this bug will be corrected though. In the mean time, I
will use a card reader.

Nedberg,

Thanks for the report. I recommend you to post a report in Gphoto2 bugzilla to fix the Canon Gphoto2 driver. Nothing can be done in this by digiKam...

Well, I have got myself a new camera. And I now only use a card reader to transfer images so I haven't seen this bug for a while. I just dug up the old Canon IXUS 850IS and made a shot.

On Kubuntu 8.04 with digiKam 0.9.3 the filename is correct! Marking as fixed!
