Samsung Tizen Plex app displays clock one hour behind following Alberta’s permanent UTC−6 change
Device: Samsung S95B (Tizen)
Plex Samsung app: 5.94.1
Location: Edmonton, Alberta, Canada
Since Alberta’s November 1, 2026 time-zone change, the Plex app’s clock in the top-right corner consistently displays one hour behind the correct local time.
Example: Samsung TV clock: 12:45 PM. Plex app clock: 11:45 AM.
The minutes match exactly, indicating a consistent one-hour offset rather than clock drift.
Troubleshooting completed:
- Samsung TV system clock confirmed correct.
- Samsung TV time zone set to Central, DST disabled.
- Tested manual clock mode with no change.
- TV fully rebooted.
- Plex app fully exited and restarted.
- Plex app uninstalled and reinstalled.
- Plex app version confirmed as 5.94.1.
- Plex Media Server runs in Docker on Synology.
- Container TZ set to America/Regina.
- UCG Ultra configured for UTC−6 (Regina).
- DNS changed to Cloudflare/Google with no improvement.
The problem appears isolated to the Samsung Plex client.
Could this be an outdated time-zone rule or incorrect UTC offset in the Tizen client?
Alberta now observes UTC−6 year-round.
