I have a minor nuisance situation. I've spent a couple of days, three timezones away from home, hiking and shooting with three cameras, one of which is a Leaf Aptus 22. I remembered to reset the date/time on the other two cameras, but not the Leaf. As I was changing between cameras constantly depending on the circumstances, it's now a nuisance to make sense of the trip when reviewing the photos - the Leaf shots are three hours 'later' than the others.
A web search shows that Lightroom allows you to bulk-offset the time metadata, and I recall that Aperture used to do something similar, but can Capture One, my preferred program? There are many third-party programs to change JPEG EXIF, but obviously that doesn't help with .MOS files.
