SUMMARY I often encounter the problem of wanting to merge sets of photos taken with cameras whose time/date was not set correctly. digiKam already offers nice solutions to deal with this, but I was wondering if you ever considered a dedicated tab for this. In particular, it would be nice to simply shift a photo back/ahead until it appears in the right place in the album, and then apply the same time shift to all photos taken with that camera. I once did some baby-steps in this direction. I never got the app mature enough but I think that it had some nice functionality : https://github.com/tdegeus/chroto
