I have installed Lightroom 3.6 Release candidate and have tried to update the metadata for the time of capture. I select a group of photos and apply changes (in my case +12 hours) and apply the changes. Lightroom appears to do this but when I check the metadata there has been no change. For the travel trips where you forget to reset the clock on your camera, this is a neat solution (if it worked). Am I doing anything wrong?
