Copying timezone from XMP to EXIF

[José Oliver-Didier]

Hello,

How can I set the 3 EXIF timezone offset values (OffsetTime, OffsetTimeOriginal, OffsetTimeDigitized) using the XMP timezone value in the XMP Date/Time Digitized, if available?

Code Select Expand

[XMP-exif]      Date/Time Digitized             : 2023:04:13 10:42:25+03:00
I know you can write to all three of these tags using:

Code Select Expand

-EXIF:OffsetTime*=+03:00

You can copy it directly

Code Select Expand

C:\>exiftool -time:all --system:all -G1 -a -s y:\!temp\Test4.jpg
[XMP-exif]      DateTimeDigitized              : 2023:04:13 10:42:25+03:00

C:\>exiftool -P -overwrite_original "-OffsetTime*<DateTimeDigitized" y:\!temp\Test4.jpg

C:\>exiftool -time:all --system:all -G1 -a -s y:\!temp\Test4.jpg
[ExifIFD]      OffsetTime                      : +03:00
[ExifIFD]      OffsetTimeOriginal              : +03:00
[ExifIFD]      OffsetTimeDigitized            : +03:00
[XMP-exif]      DateTimeDigitized              : 2023:04:13 10:42:25+03:00

Is there an easy way to do this in the reverse? So appending the time zone in OffsetTime to an XMP time field that is missing the time zone.

Like this?:

exiftool "-xmp:createdate<$xmp:createdate$offsettime" FILE

Alternatively, if both EXIF:CreateDate and EXIF:OffsetTimeDigitized exist, then you could use
exiftool "-xmp:createdate<SubSecCreateDate" /path/to/files/

SubSecDateTimeOriginal/SubSecModifyDate would also be possible tags.  Though if any subsecond tags existed, they would also be included.
