Server Version#: Version 1.30.0.6442
Player Version#: All client but for testing I’m using web client version 4.96.2
Setup:
- Media is mp3 music files, not flac.
- Using
Prefer local metadatafor music media and all are tagged using musicbrainz picard. - Using ID3v2.3 with UTF-16 tags due to ffmpeg bug (#6949 (No support for multiple values in ID3v2.4 tags.) – FFmpeg ) with multiple values and ID3v2.4.
Steps to reproduce:
Tag an album with the date of 1969-12-31 or 1970-01-01 and plex dance the album into plex.
Using the client now sort by album → by release date (reverse order). See screenshot below:
If you look in detail at the screenshot you will see the albums on the first row do NOT you have a release date shown whereas the ones the second row do.
If you edit one of these albums in plex you can see the date is present but the plex client does not recognise it when sorting.
Workaround:
Edit the tag to use 1969-12-30 or 1970-01-02 instead. See example with second to last album after changing the date to 1970-01-02,
Most likely a bug (or a design decision) with how plex handles epoch date formats with the change from positive to negative numbers.
