Bug ID: 476390
Summary: Non-destructive date information management
Classification: Applications
Product: digikam
Version: 8.2.0
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: Metadata-Date
Assignee: digikam-bugs-n...@kde.org
Reporter: lk.digi...@mailnull.com
Target Milestone: ---
SUMMARY
This is a request for a non-destructive original date storage when editing the
metadata for files that don't have date information in them.
If digikam would store a "first seen" row in the database, it could be used to
restore timestamps, even if metadata operations overwrite them in the file.
Example usecase:

STEPS TO REPRODUCE
1. Import an album that has pictures without EXIF date information, only the
file modified date as picture original date.
2. Apply metadata transformations to the files without unchecking "Update file
modification timestamp when files are modified".
3. Try to apply date manipulations to the files afterwards.
OBSERVED RESULT
4. Notice the original file dates are not stored anywhere to be used as
information for date manipulation.
EXPECTED RESULT
5. User could have the option to read the "first seen" file date (eg.: from a
new digikam database row?)

ADDITIONAL INFORMATION
This report includes a suggestion for the resolution, but the impetus is to
have a way to restore lost original timestamp information performed by user
actions. Note that this is not a request to undo steps in timestamp operations
(ie.: store all editing steps), only to store the first original timestamp as
seen by digikam when importing an album, assuming that this should be easier to
implement and already useful as a safeguard and utility for date manipulation
(eg: using the time stored but changing the date for all images could be done
with this information).
