The problem is caused by the timezone setting being different at the android layer and at the ubuntu layer. The android layer seems to always use the UTC tz, and that is what it writes in the EXIF tags when it returns the encoded jpeg data to libhybris.
The attached branch fixes the problem by updating the EXIF tags with the correct timestamps in qtubuntu-camera, before saving the image to disk and notifying the apps. However according to ogra there might be a way to fix this by making sure we set the tz in android too when we set it in ubuntu. <ogra_> phablet@ubuntu-phablet:~$ sudo lxc-console -t0 -nandroid <ogra_> root@mako:/ # date <ogra_> Wed Sep 24 10:51:11 GMT 2014 <ogra_> root@mako:/ # setprop persist.sys.timezone Europe/Berlin <ogra_> root@mako:/ # date <ogra_> Wed Sep 24 12:52:15 CEST 2014 <ogra_> seems it uses the same notation <ogra_> (but to verify 100% one would likely need to check the source of bionic or so ) The tz names in bionic are as follows: https://gist.github.com/arpit/1035596 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtubuntu-camera in Ubuntu. https://bugs.launchpad.net/bugs/1371390 Title: pictures taken with camera have wrong timestamp Status in QT Ubuntu Camera: New Status in “qtubuntu-camera” package in Ubuntu: In Progress Bug description: krillin rtm build 46 - phone is set for Eastern time zone (utc -4) - take a picture with the camera - apt-get install exiv2 onto the phone - cd ~/Pictures/com.ubuntu.camera - exiv2 <imagename>.jpg Expected results: Image Timestamp in meta data should match the local time on the phone, with TZ offset applied Actual results: Image Timestamp is 6 hours ahead of my timezone The problem with this is the gallery app uses the timestamps found in the exiv data to display events, so a photos are showing up on the incorrect day To manage notifications about this bug go to: https://bugs.launchpad.net/qtubuntu-camera/+bug/1371390/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
