| Oct 30, 2020 at 17:58 | comment | added | Michael | @MichaelScheper How do you do that exactly? It seems Google ignores the GPS timestamp (which is supposed to be set to UTC) | |
| Jun 23, 2019 at 10:21 | comment | added | Michael Scheper | Actually, it seems that Google Photo, and sometimes Facebook, tries to infer timezones from geodata, and assumes that the EXIF time is in that timezone. That's my best guess for why it seems to mess up the timestamps so badly, anyhow, since I try to keep EXIF timestamps UTC. | |

The user can set whatever Time Zone they want to see, but it is not otherwise detectable by external direct observation. That's what makes it difficult to add to Exif too. Yes, I did err in assuming GPS timestamp, since of course we do know our own Time Zone, but Time Zone can confuse it when traveling. | |

| Feb 19, 2018 at 14:51 | comment | added | WayneF | Time Zone is Not an observable feature, a difficulty of course assumed to apply to GPS satellites too. :) | |
| Feb 19, 2018 at 5:39 | comment | added | Caleb | The OP didn't ask why the camera doesn't determine time zone from GPS data, they asked why the time zone isn't recorded in the EXIF data. Many cameras let the user enter time zone along with the date and time; including that information in the EXIF info would presumably be pretty simple. | |
