Description Rick Wagner 2009-05-23 08:55:06 UTC

Version:           0.10.0 (using KDE 4.2.3)
OS:                Linux
Installed from:    Fedora RPMs

My system is in GMT-7 timezone.  I had some pictures which I originally imported into KDE 3.5.? version Digikam, and geolocated with the correlator using .gpx files.  In that version, setting the timezone to GMT-7, the images correlated correctly.

Due to a disaster of my own doing, I lost the above edits.  Fortunately, I still had the original media.  So I took the opportunity of my disaster to upgrade to KDE4.2 and DigiKam 0.10.0.  When I attempted to again correlate the same images, many would not correlate; and those that did were wrong.  Looking at the times, it seemed that the correlations were 7 hours off.  So I set the timezone to GMT-0, and the images correlated correctly.

To double check, I took the exact same (gelocation removed) JPG's and .gpx files back to another Fedora-8 (KDE 3.5, older digikam), and they correlated with GMT-7.

It appears that in 0.10.0 the correlator is taking local timezone into account when loading the GPX files.

I can confirm this behaviour also in Ubuntu 9.04 amd64 (KDE 4.2.2, GPS Sync 0.2.0). HW clock is set to GMT, local time zone is GMT+2 (incl. daylight saving time).

I suspect GPS Sync uses hw clock instead of local time and in this particular case the Time Zone adjustment does not make sense.
