I've run into an issue where Emby is using the file's Date Modified field for sorting instead of Date Created. I've tried setting both the "Use file creation date" and "Use date scanned into library" options under "Date added behavior for new content" but they don't make any difference. I've attached an example below...this is the last file added to my library but it is appearing in the list as if it were added on December 5 instead of December 23. Looking at the metadata for the file, it shows
This is the reason: https://github.com/dotnet/runtime/issues/80023
When the .NET runtime can't determine the file creation date on linux, it silently falls back to the last modified time, and there's no way for us to stop that. It would be better if it threw an error so that we could decide how to proceed, but it's just a silent switch that we can't control.
So we will need them to resolve that, although it doesn't look like they want to change the behavior right now.
