Your phone might store the timestamp in a different format (e.g. localized), so make backups of the files before, and if the script does not work, use the "strings" command to see what the format is like.

This way, all my photos always have the correct time information - and not the information about when it has been transferred to the computer.

It would be nice if someone could
* make the script more generic (possible use a better method to extract the date)
* include this script into the AppleScript in the article.
