Re: change EXIF data

Digikam will let you edit date and time... it's a KDE photo management program like F-Spot or Picasa. I don't know of any others.

As for the CLI tools most will dump Exif data, or adjust date/time as on offset of the original EXIF stamp:

Code:

# to dump exif data
$ exiv2 -p s filename.jpg

# adjust date/time +1 day (in hours)
$ exiv2 ad -a 24 filename.jpg

## or use jhead ##

# to dump exif data
$ jhead filename.jpg

# adjust date/time
$ jhead -ta+24 P1000616.JPG

IMHO, jhead is much more capable, and provides more control over date/time (see the '-da' option).

Hope that helps.
