Ursache: Container lief in UTC, waehrend die Flux-Aggregation Europe/Berlin nutzt. Dadurch lagen die in JS (Lokalzeit) berechneten Monats-/Tagesgrenzen eine Stunde neben den Flux-Balken: - Januar-Balken (Berlin = 31.12. 23:00 UTC) lag vor 'start' (UTC) und wurde weggefiltert. - Ladetag-Zeitstempel (UTC-Mitternacht) passten nicht auf die Verbrauchsbalken (Berliner Mitternacht) -> keine Markierung. Fix: tzdata ins Image + TZ=Europe/Berlin (Dockerfile und compose). Damit stimmt die JS-Lokalzeit mit der Flux-Location ueberein. Verifiziert: im Container ergibt new Date(2026,0,1) den Berliner Monatsanfang. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
