Where is my mistake?


I Imported GPS-Tracks to Aperture. The Track is allways GMT- Timezone!

When I changed the Timezone to MEZ and Aperture was New started, the Timezone is allready in GMT?!


I work with myTracks and there the track ist o.k.

The Track comes from iPhone, and I logged the Track with komoot.


So i cannot put the pictures from my EOS 7D to the Track.


Is there a Bug in Aperture?

iMac, OS X Mountain Lion (10.8.2), MBpro

    Could you please explain in more detail, what the problem is?

    In what way is the handling of tracks imported from your iPhone in Aperture wrong?

    I Imported GPS-Tracks to Aperture. The Track is allways GMT- Timezone!

    That is how it should be - GPS tracker are recording the Tracks in UTC.


    What is the timezone of the times on your photos, and what the original timezone of your tracks, before you adjusted them?

    It is buggy. Aperute should be able to interpret the times correctly, when you do this:


    • When you import the photos, set the time zones correctly in the import settings - in your case: Camera time = MESZ, Actual Time = MESZ. So Aperture will know, how to interpret the time stamp on your image files.
    • When adding the track, set the "GPS > Edit Timezone" to the timezone setting of the track you added, not to the timezone of your photos.


    What I am seeing, however, is that Aperture erraniously seems to be using the Timezone of the system time, when comparing the dates, not the timezone set in the "Import" panel.


    For example, my camera is set to UTC, all import settings are UTC, the track is UTC, and still the times are off by one hour along the track, when dragging an image there:

    The track is showing the correct time, when I hover the mouse over the track - only the time difference to the photo is computed incorrectly, by one hour.

    The correct time, shown by the track:

    But a difference of -69 minutes to the date of the image.

    please excuse my bad english, but i have not enough practise

    No problem - we are in the same boat here!


    • the import setting is allways on

              Time of camera: Europa/Berlin (MEZ, now MESZ))

              real time: Europa/Berlin (MEZ, now MESZ)

    That should work. I am only using UTC, because that timezone does not continuously change with daylight saving time, and because I am traveling a lot and by keeping all cameras always set to the same timezone I do not have to worry about forgetting to adjust the time.


    Feedback to Apple is a good idea.

    I took a photograph using my iphone4s to see if I could import GPS from my iphone and in Aperture I tried clicking on "Import GPS from iPhone Photos" and it tries to connect but with no success, do you think that Apple has solved this problem? or is it me?

    Geotagging in Aperture is pretty much a mess. There's no way to say: my photos and GPS tracks are both in UTC and I've synched my clocks—just match them up. Using UTC is important because it's the only time zone with out the daylight savings time nonsense.


    I've found it best to geotag my photos outside Aperture so that they already contain the info when imported. If you're familiar with the command line, you can use exiftool thusly:


    $ exiftool -overwrite_original_in_place -geotag my-track-file.gpx *.ORF


    Replace "ORF" with the extension of your raw files. You have to do everything in UTC for this to work.
