I've had issues with my movies on the last two Panasonic cameras I've owned, (the latest is a DC G100 that I'm quite pleased with), showing up 8 hours before, (in file listings), pictures that were taken right next to them (in the scheme of actual time.) I figured out that there are other date fields availabe in the file viewers that have the correct time. Here's a video short of how to to do that. Maybe I'll ask ChatGPT if there's a way to code up something that will make the dates actually match across all the fields later.
