Hi,

I would like to know if it's possible to modify a portion of a tag.
Actually, I'd like to set the date of FileModifyDate and AllDates without modifying the time.

Thank you

David

To do this would require a user-defined tag to extract the time from
a date/time value. You could then set the date like this:

Code:

exiftool -alldates<"2007:03:04 $mytime" FILE

(Note: use single quotes in Unix, double as above in Windows)

The following config file will allow you to do this:

Code:

%Image::ExifTool::UserDefined = (
'Image::ExifTool::Composite' => {
MyTime => {
Require => 'DateTimeOriginal',
# remove the date
ValueConv => '$val=~s/.*? //; $val',
},
},
);
1; #end

See the config
file documentation for instructions on installing the configuration file.
