TMDB stores air dates as bare date strings (e.g. '2026-04-26') representing the local air date in US Eastern time. For viewers in timezones ahead of the US, shows airing Sunday evening US time would display the wrong day. Changes: - Add ConvertTmdbDateToIso() method that interprets bare TMDB dates as 9PM US Eastern and converts to ISO 8601 UTC timestamps - Apply conversion to nextAirDate, digitalReleaseDate, theatricalReleaseDate, and initialAirDate in TMDB enrichment - Browser's new Date() then automatically maps UTC to viewer's local day - No configuration needed — works automatically for all users Example: '2026-04-26' (US Sunday) → 2026-04-27T01:00:00Z In NZ (UTC+12): shows as Monday April 27 ✅ In US ET: shows as Sunday April 26 ✅ Fixes n00bcodr#315

There was a problem hiding this comment.
This is based on the assumption that all shows air at 9PM which might not be the fact?

Problem
TMDB stores air dates as bare date strings (e.g.
"2026-04-26") representing the local air date in US Eastern time. For viewers in timezones ahead of the US, shows airing Sunday evening US time would display the wrong day.For example, a show that airs Sunday 9PM ET is listed as
"2026-04-26"by TMDB. For a viewer in NZ (UTC+12), that episode actually airs Monday 1PM NZST — but the Coming Soon and Requests views would incorrectly show "April 26" (Sunday) instead of "April 27" (Monday).Solution
Added
ConvertTmdbDateToIso()which interprets bare TMDB dates as 9PM US Eastern and converts them to proper ISO 8601 UTC timestamps. The browser'snew Date(dateStr)then automatically maps to the viewer's correct local day.No configuration needed — works automatically for all users.
Example:
"2026-04-26"→2026-04-27T01:00:00ZChanges
JellyfinEnhancedController.cs— AddedConvertTmdbDateToIso()method that interprets bare dates as 9PM America/New_York and converts to UTC. Applied tonextAirDate,digitalReleaseDate,theatricalReleaseDate, andinitialAirDatePluginConfiguration.cs— Minor: reordered field placement (no new config properties)configPage.html— No UI changesBackward Compatibility
