Description José Oliver-Didier 2020-11-15 00:33:01 UTC 
SUMMARY
Exif 2.32 Time Zone value names do not appear in the EXIF panel.

STEPS TO REPRODUCE
1. Obtain an image with Exif 2.32 TimeZone values (Example: Refer to attached image taken with a Pixel 3 Phone)
2. In digikam, view the EXIF properties panel under Photograph Information. 


OBSERVED RESULT
Exif time zone values appear, but the value names appear as:
0x9010
0x9011
0x9012

EXPECTED RESULT
Correct label names:
0x9010 should read OffsetTime
0x9011 should read OffsetTimeOriginal
0x9012 should read OffsetTimeDigitized

ADDITIONAL INFORMATION
Comment 1 caulier.gilles 2020-11-16 06:48:37 UTC 
The problem is due to missing implementation in libexiv2 which do not recognize yet these tags.

Please report this problem to Exiv2 team as an UPSTREAM bug.
