Comment 1 for bug 1371390

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_> seems it uses the same notation

The tz names in bionic are as follows: https://gist.github.com/arpit/1035596
