Conseils et bonnes pratiques
- IANA timezone names like "America/New_York" handle DST transitions for you — they're city-based, not offset-based.
- Fixed UTC offsets (e.g., UTC+5) ignore DST. Use IANA names for places that observe daylight saving.
- Some zones change rules: e.g., Russia ended seasonal time in 2014; the IANA database tracks the historical rules.
- When in doubt, use the closest large city for the timezone you want — populated places stay in the IANA database.
- Everything is computed locally using the browser's timezone data; no API call is made.
