Bug ID: 467601
Summary: Add an optional time zone field to the renaming dialog
to indicate the time zone to use for renaming
Classification: Applications
Product: digikam
Version: 8.0.0
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: AdvancedRename-dialog
Assignee: digikam-bugs-n...@kde.org
Reporter: mcfaro...@gmail.com
Target Milestone: ---
PREAMBLE
Let say you make a quicktime video at t, in a country which time zone is tz
with a device set to the local time.
According the type of the device (smartphone, digital camera, ...), time
written into metadata (tmd) by the device will be :
1) tmd = t - tz ; no time zone metadata set
2) tmd = t - tz ; time zone metadata = UTC
3) tmd = t - tz ; time zone metadata = tz # I don't know if there are devices
doing that
4) tmd = t # digital cameras which are not able to get by itself the current
tz (or don't let you set the current tz)
DESIRED BEHAVIOR
I would like to rename the video with the local time of the shooting using, for
example, [date:yyyy-MM-dd_hh'h'mm-ss] pattern regardless of the tz of the pc
where digikam is running. It seems to be a logical use case.
CURRENT DIGIKAM RENAMING BEHAVIOR
Let say T is the time digikam will use to build the filename and pctz the
current time zone of the computer where digikam is running.
For some devices such as android devices : T = tmd + time zone metadata if it
exists (mdtz) + pctz
For others devices : T = tmd
So, if you make a video at 10:00:00 local time with an android device (which
doesn't set mdtz or set mdtz = UTC) traveling in a country where time zone is
UTC-5 and you want to rename the filename of the video when you come back to
your country of residence which time zone is UTC+1, you will get a filename
with 16:00:00 time, no 10:00:00. The only way to get it would be to modify the
metadata time of the video to 09:00:00 (instead of 15:00:00) so that digikam
produces the desired 10:00:00 time.
WISH
Add an optional time zone field to the renaming dialog to indicate the time
zone to use for renaming (if empty, digikam would use pctz).
