I believe the answer is no, but can the R5 automatically switch its onboard clock 1 hour forward in March, and back again in November?

The only way that could happen is if the camera had a continuous cellular or internet connection.

No.

After the date, time, and location were set, all that would be needed would be the rules for that location.

I have a (low-end) remote weather station. It has no Internet connection, and it receives no time signals. It automatically does DST, using the standard that applies to most of the US. (DST can be turned off, for those places like Arizona that don't switch.)

If the rules change, it won't work correctly. I believe that the last change was in 2007.

Yes, that's "all" that is needed. Unfortunately, that would require a firmware update every time some country or part of a country decided to change their rules. So not practical. Major software companies whose software has access to the internet sometimes get the rules wrong.

The camera does both. Your images will have the time for the time zone you set as well as UTC.

I can't seem to find the time zone anywhere in my EXIF data.

There may not be time zone data, but there are both UTC and the local time the picture was taken. You can see it by reviewing the images on the camera itself. Press INFO to get all the details and you'll see the local time above the histogram. Scroll to GPS info in the lower area of the screen and you'll see UTC.

Garmin devices have to be updated frequently enough that they are going to have the correct local time. Camera firmware is only updated when there's an update, and that's not every year and frequency becomes much less often as the camera ages.

In more recent devices Garmin has handled that by having the time zone data separate from the main firmware. Older Garmin units, but still new enough to implement this scheme, typically receive time zone updates and only that. The main firmware of the device is not updated any longer.

They also update themselves more of less automatically. The only thing the user needs to do is confirm loading of the update.
