Description Julian Klein 2008-04-20 08:14:39 UTC
Version:           0.9.3 (KDE 3.5.9 "release 57.3" openSUSE) (using KDE 3.5.9)
Installed from:    SuSE RPMs

Geotagging images with digikam worked well (except Bug #158329) until daylight saving time (DST) showed up.
My GPS device stores the timestamps in a timezone, which is two hours behind german DST (MESZ). (Is this UTC?) I can't figure out a way to put this together with the timestamps of my photos (which are in MESZ). I've tried every timezone in digikam's geotagging dialog between GMT-5 and GMT+5 and many combinations of timezones and interpolations. It always says, that it can't find any pictures, which correlate with the informations from the GPX file.

I tried with latest svn version of digikam and gpssync kipi-plugin and it works perfectly...
Chris, when using DST, the timezone change from GMT+1 to GMT+2 (western europe).
I just used GMT+2 and it's ok (max gap to 30s).

Usually, gpx files contains UTC time only.
You have :
Image timestamp : 2008:04:15 17:23:11
and
<trkpt lat='52.46545' lon='13.32668'><ele></ele><time>2008-04-15T15:23:05Z</time></trkpt>
You need max gap to be at least 7s.

For me it *don't* work with timezone GMT+02:00 and gap of 30 sec.
GPS Sync version: "Kipi-plugins 0.1.5rc1", digikam version as described above. Thats the newest version I've got via openSuse RPM repositories.
Comment 5 Julian Klein 2008-05-11 11:59:33 UTC
Works for me now with "GPS Sync" 0.1.5 and digiKam 0.9.3 (KDE 3.5.9 "release 60.3" openSUSE)
