Immich uses exiftool for determining the time(zone) of an asset, which I believe takes location into account as well.

Is exiftool used again for jpeg+xmp, when a new location is set?
When xmp is deleted and metadata refreshed, time returns to the original timezone.

GPS data is almost always assumed to be the most accurate way to determining an image's time zone. This image has "DateTimeOriginal": "2011:10:06 15:30:04", which does not include any offset, so it is assumed to be local time. The fact that is it adjusted based off of location is expected behavior.

The example image has Time Zone Offset: 3 and timezone is properly displayed before adding location...

Current behaviour is not expected. Image timezone is overwritten by location TZ within Immich DB exif table and then not interperted and shown correctly (see Immich and DB table screenshots). There is shown Europe/Prague (+02:00) although Asia/Jerusalem is stored. This is definitele a bug.

The server is working correctly, the client is not using timezones properly. I'm pretty sure we're tracking this in another issue though.
