Version: 1.2.0 (using KDE 4.4.5) OS: Linux It would be nice to have time zone support. I take some pictures in different timezones and would like to be bale to have the "local time" of the picture as well as the time zone it was taken in. I know some other softwares does this by; * storing "local" date and time in EXIF "Date and Time" * storing "UTC" date and time in EXIF "GPS Date Stamp" and "GPS Time Stamp" respectively * figuring out the time zone from the UTC and local time Reproducible: Always
This is a job for digiKam DB properties, to dispatch later to plugin... Gilles Caulier
still valid in 2.8.0. got a mixup of chronological order when traveling timezone.
Now that time zone is supported in the new EXIF standard it would be nice to revisit this bug. EXIF 2.32 Time Zone fields: 0x9010 OffsetTime string ExifIFD (time zone for ModifyDate) 0x9011 OffsetTimeOriginal string ExifIFD (time zone for DateTimeOriginal) 0x9012 OffsetTimeDigitized string ExifIFD (time zone for CreateDate) Also, timezone are supported in XMP dates.

Adding comment from Bug 377857 The MWG 2.0 spec (the group seems to have disbanded, but the spec is still referenced) has some thoughts on timezones on page 33. https://s3.amazonaws.com/software.tagthatphoto.com/docs/mwg_guidance.pdf Also, something which I stumbled upon some time ago: "TimeZoneOffset is a non-standard tag that was made before the EXIF standard actually added time zone tags. There are three time zone tags, EXIF:OffsetTimeOriginal, EXIF:OffsetTime, and EXIF:OffsetTimeDigitized, which correspond to EXIF:DateTimeOriginal, EXIF:ModifyDate, and EXIF:CreateDate respectively." https://exiftool.org/forum/index.php?topic=13170.0

Maik, What's about this file and other ones related to this topic ? These can be closed now ? Gilles
No, it cannot be closed yet. Only a necessary database update was performed; the code to handle time zones still needs to be written. I am planning to do that in the autumn. Maik
