XnView Software

I took some pictures with my camera using daylight saving time instead of standard time. I was able to easily correct the time on the files using Total Commander and a plugin. But now I also want to set the EXIF data back by one hour. I don't know how to do this with XnView MP 1.9.5. Both Perplexity and ChatGPT provided me with instructions that don't work. The search function here in the forum hasn't helped me either. How can I use XnView MP to either reset the Exif time by one hour or set the Exif time to the file time?

Thank you in advance!

Best regards from Germany!

Thanks, Pierre!

The German translation of "Change timestamp" is a little bit confusing: "Dateidatum und -uhrzeit ändern". It should be: "Datum und Uhrzeit ändern"!
