Change creation time back one hour

I forgot to set the time back one hour for Daylight Saving Time on my camera last night and now I have several photos with creation times the are off by one hour. Is there a way to select a group of photos and tell digiKam to edit the creation time back one hour? Item > Adjust Time & Date… , looks like a good place to start, but I can’t figure it out.

Sorry, I don’t know if that can be done by digicam, but exiftool can do:

for i in *JPG; do exiv2 -a “1:0:0” $i ; done

This tool works very well, I did use it to change EXIF for the same reason that you mentioned a couple of times. But you have to be careful with the options so I suggest you make a test album and try those out to see how it works.
