For my mirrorless Canon R5, when I import MP4 videos from my camera into Synology Photos, the timeline view shows the files in my computer’s timezone, not the timezone the photo was taken. The EXIF data is correct, reflecting the correct GPS data for Beijing, China. I live in Seattle, WA. The photos are appearing in the timeline as though they were taken in Seattle time (e.g. 15 or 16 hours earlier). So these videos were really taken at 2pm Sep 7 Beijing time, but showing up as being taken late at night on Sep 6, which was the time in Seattle at that moment. There appears to be no setting to make Timeline honor the local time the video was shot. This does not happen for photos.
