Comment (by cus):
When you specify creation time in the CLI, it is interpreted in local
timezone, therefore it is recalculated to UTC before saving it in MOV. So
after my patch, the correct UTC time is stored in MOV.
Unfortunately when ffmpeg reads creation time metadata from mov, I guess
it presents the UTC time, but without specifying it, that it is in UTC.
The correct fix would be to fix the mov demuxer (and all demuxers having
the same problem) to set the creation_time to an ISO 8601 compatible
timestamp.
Which other muxers are affected? I might work on this.
