           Summary: Digikam treats .MOV files differently from .JPG files
                    by modifying timestamp in metadata to match local
                    time, when video was taken in a different time zone

I have a combination of JPEG and MOV files taken with an iPhone, in both
California and Scotland. I live in Connecticut. The timestamp on the phone, as
well as in the OS X Finder after I upload them at home, displays the date and
time they were taken in those locations. But when I load them into Digikam and
try to group them together in albums sorted by date, they don't sort correctly.
The metadata for the video files from California shows a time 3 hours later
than the time they were taken, while the video files from Scotland show a time
5 hours earlier. In effect, both appear to be adjusting to EST based on the
original GPS location of the photos/videos. But JPEG photos taken at the same
time with the phone do not show this adjustment, as the metadata correctly
shows the time the photo/video was shot in that time zone. As a result, without
manually adjusting the time in the metadata for each of these videos, they will
not sort properly alongside photos taken at the same time.
