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?
[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:
-EXIF:OffsetTime*=+03:00
You can copy it directly
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
Thanks!
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.
