The audit showed only 5 of ~11 time-display surfaces converted to the user's timezone; everything else rendered pgx-decoded UTC. The server owns conversion — clients (web/app/KOReader) receive display-ready strings or machine-readable instants and never convert. - Progress page: LastUpdated formatted in the requesting user's tz (was raw UTC). - Analytics: date-range defaults, day buckets, most-active-day, device last-sync, and popular-book last-read all computed in the user's tz — evening sessions no longer land on the next UTC day. Also fixed the end-date boundary: the query bounds with <= and the end bound was midnight, so the end date's own sessions (including 'today') never appeared. - Queue page: new created_at_display field (admin tz) rendered by the template; created_at stays RFC3339 for API consumers. - Admin hash-conflicts SSR bridge: detected date rendered in the admin's tz. - OPDS: .UTC() before the Z-suffixed feed timestamps (honesty fix — correct today only because the session zone happens to be UTC). - KOReader annotation datetimes deliberately untouched (device owns its display).
