I would like to report a bug in Lightroom 6.
When you modify the date of a bunch of photos and then create a panorama or an hdr image with several of these photos, the resulting image's date/time is based on the original date and not the corrected one. So you then have to go and look for the resulting panorama or hdr, and edit its date/time.
It is a very anoying, and I believe, erroneous behavior.
