Hallo Phil,
The Olympus camera OMD EM5iii writes all -exif:offset... tags with values: " : ".
This is allowed by EXIF standard and means: value is unknown.
Exiftool 12.03 displays these values as:
OffsetTime : :
OffsetTimeOriginal : :
OffsetTimeDigitized : :
For me it is a little bit difficult to realize the value " :" (trailing spaces are removed).
So I would like to propose to display these values as "--:--".
Thanks in advance and
Best regards
herb
Hello,
No comment!?
Is it really a bad idea?

Somehow I missed this post.
I don't really like the idea of changing the spaces to dashes in the time. I would have to check the specification, but spaces are valid in other date/time fields and ExifTool doesn't translate these either.

Hello,
Thanks for your comment; I understand.
My proposal was based on the fact that ExifTool removes the trailing spaces after ":" in case of display. So it is difficult to "recognize" the ":".

Hi Herb,
Why is it difficult to recognize the ":"?
- Phil
Other options would be using -api "Filter=s/ /-/g" to swap spaces for hyphens, though that would be global.
The other option would be to make user defined tags for these to do the swap.
%Image::ExifTool::UserDefined = (
'Image::ExifTool::Composite' => {
MyOffsetTime => {
Require => 'OffsetTime',
ValueConv => '$val =~ s/ /-/g;$val',
},
MyOffsetTimeOriginal => {
Require => 'OffsetTimeOriginal',
ValueConv => '$val =~ s/ /-/g; $val',
},
MyOffsetTimeDigitized => {
Require => 'OffsetTimeDigitized',
ValueConv => '$val =~ s/ /-/g;$val',
},
},
);

Edit: Updated config file so it will pass through original data if no changes are made
Hello Phil, hello StarGeek,
@StarGeek: Thanks for your proposal; But I think only on tags that represent a timezone-value.
QuoteWhy is it difficult to recognize the ":"?
Looking at the following timezone-values
tag1 : +01:00
tag2 : :
tag3 : --:--I thought that tag3-line looks better than tag2-line. That's all.
Thanks and best regards

I agree, but I don't think this is worth changing, especially because people familiar with the EXIF specification may expect spaces.

@StarGeek: Thanks for your proposal; But I think only on tags that represent a timezone-value.
That's why listed a config file. It only affects the three OffsetTime tags. Example output:
C:\>exiftool -config MyOffset.config -g1 -a -s -offset* -myoffset* y:\!temp\Test4.jpg
---- ExifIFD ----
OffsetTime : +07:00
OffsetTimeOriginal : :
OffsetTimeDigitized : +07:
---- Composite ----
MyOffsetTime : +07:00
MyOffsetTimeDigitized : +07:--
MyOffsetTimeOriginal : --:--
Hello StarGeek,
Yes, you are right; I should have thought on user-defined tags at the very beginning.
Best regards
