Re: DST on R5

Watches with GPS (not smart watches) from Casio, Seiko do it decades ago.

They time-zone-ed any location on this planet. The watch change the time according to the location they are at.

Not so many places change the time zone every year, actually, it's very rare. As I known, North Korea had ever done it. And some territory changes may cause time zone or DTS change.

Some old model watch with GPS may run the fixed timezone-coordination table forever. New model mostly are Bluetooth + GPS (again, not talking about the smart watch) bundled, they do update the time zone table any time if needed.

The timezone - coordination is not as simple as it looks, only timepiece maker have it in detail and update it frequently. They don't share it, it's the result of many years running and calibration.

Smartphone/smartwatch gets the time zone from the mobile network or wifi network, even the phone nearby. They can set the time zone very fast if they are connected. They can not do it without connection even it can receive the GPS, for example, on an aeroplane.

For camera maker, the coordinated timezone is out of their duty, the price of the camera is not included. They leave it done by users manually.
