Where does Immich get the timezone from in MOV files?
I’m trying to figure out how Immich detects the timezone for MOV videos.
I have two .mov files, both shot on an iPhone:
One shows the correct timezone in Immich (GMT+2, Paris)
The other one doesn’t — it just shows the time with no timezone info, so it ends up being off by a couple of hours.
I tried fixing it with exiftool by writing timezone info into a bunch of fields (QuickTime, Track, Media, Keys, UserData, XMP, FileModifyDate, etc.), but no matter what I do, Immich still ignores it after a metadata rescan.
So I’m wondering: Which exact tag does Immich read the timezone from for MOV files? I’d like to replicate whatever iPhones do so that the timezone shows up correctly.
