And this is why I love this community . . . When I first noticed this issue, I wondered if someone messed with my meds or turned down my oxygen or spiked my Columbia Supremo or something.

Now thinking about it, I have an older Nikon Point and Shoot camera, and it has a dual time zone feature for exif timestamping: one for home and one for travel that you only think about setting maybe halfway through a trip. It's related to the Daylight Saving setting that I remember to change after taking a few months' worth of pictures.

But that made me think some more. The phone has a distinct advantage over that old camera, it has several ways of knowing where it is, and if I leave home it could potentially ask me if I wanted to use my home time, the local time or UTC. (Just "talking out loud" as the salesmen at an old job used to say.)
