           Summary: wrong date when renaming downloaded pictures
           Product: digikam
           Version: 1.1.0
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: bugreports at familie-becker.eu


Version:           1.1.0 (using KDE 4.3.5)
OS:                Linux
Installed from:    Gentoo Packages

Digikam 1.1.0
Camera: Canon Ixus 70

I'm downloading the pics from my camera via Digikam and automatically rename
them to their corresponding exif date, rename string is
"[date:yyyyMMdd-hhmmss]". Now I have the problem that the new name is one hour
in the future.
Example: Exif date is 20100516-120000, file name is 20100516-130000.jpg

Looks like I also found out the reason:
Living in Germany, we have summer and winter time (one hour difference). In the
camera you can also toggle summer time, which adds +1h to the time. Error
occurs only if summer time is switched on in camera, else not (even with same
picture).

Extended Example:
1. Camera Time 11:00h
2. Toggle summer time switch in camera: 12:00h
3. Take picture. Exif time displayed for picture on camera is 12:00h
4. Download picture with Digikam. Exif time still 12:00h, picture named as
13:00h

As the file contains the right exif time after downloading, I would say this is
a Digikam bug and not related to the camera, as Digikam also displays the right
exif information, but obviously does something wrong when renaming the file.
