After to decide that a QuickTime date of a given video is UTC (which is not
easy, I agree), Digikam uses the local time of the PC to calculate the "local"
time of the video. This "local" time is incorrect if the video was been taken
in a foreign country (with a time zone different from that of the PC). This
incorrect "local" time impacts 1) the sorting by date 2) the renaming with
format such as [date:yyyy-MM-dd_hh'h'mm-ss].

The more logical way for the user to manage this "travel" use case is the
following :

When he come back to his country, he adjusts the dates of his travel videos he
know they have a true UTC QuickTime date (i.e. from smartphones) in order to
set them to the right local time (offset = QTdate - timezone&dst of the foreign
country). But this way, he cannot rename these videos with a format such as
[date:yyyy-MM-dd_hh'h'mm-ss] because Digikam is not aware the date are local
time now.

So I workaround the problem adjusting the date of these videos with an offset =
TZ of the foreign country – TZ of my PC. This way I can then to rename the
videos with a format [date:yyyy-MM-dd_hh'h'mm-ss]. Sorting by name (not by date
!) allow me to displays the photos and videos of a travel with the right
chronology.

I think the best solution is the first one (adjust to local time) and add an
option to the rename function to notify Digikam not to adjust Timestamp Updated
with the local time of the PC. This way I can also sort/search by date
consistently within a travel sequence.
