Re: Date and Time on importing

[Paul Wellner Bou <paul purecodes org>]

Hello,

This bug is annoying me so I tried to find workarounds and I am 
searching for the cause of this bug.

I found a workaround: The date is recognized well by F-Spot if the image 
file is modified with exiv2 or exiftool before importing it. There is no 
need to change any values, just to overwrite an exif tag with the 
existing value, for example.

No I have two photos. F-Spot does not recognize the date of the original 
(original.jpg), but it recognizes the date of the modified 
(modified.jpg) one.

What is the decisive difference between the two files? If someone has a 
little hint or an idea to diff the meta information more precisely or 
whatever... would be great. I have no idea.

The diff of the exiftool output is following:

$ diff original.exif.txt modified.exif.txt
2c2
< File Name                       : original.jpg
---
> File Name                       : modified.jpg
5c5
< File Modification Date/Time     : 2008:06:02 21:24:32
---
> File Modification Date/Time     : 2008:06:02 21:39:57

< Thumbnail Offset                : 7820
---
> Thumbnail Offset                : 7844

I uploaded the files here:
