This can be done with a user-defined tag and the following
config file:
%Image::ExifTool::UserDefined = (
'Image::ExifTool::Composite' => {
ShiftedTime => {
Require => 'DateTimeOriginal',
ValueConv => q{
require 'Image/ExifTool/Shift.pl';
Image::ExifTool::ShiftTime($val, '0:30', -1);
$val =~ s/^\S+\s+//; # remove date
return $val;
},
},
},
);
using this command line:
exiftool "-caption-abstract<shiftedtime" FILE
See the config
file documentation for help with installing the config file.
