Open-source Timezone API (no keys) — CORS-ready + offsets
Posting a handy GitHub repo for here a free world time JSON API.
What it does: timezone-aware responses, DST status, UTC offsets, plus an IP-to-timezone endpoint for auto-detecting the user’s local time. No signup needed, and it’s browser-friendly via CORS for frontend fetch. :contentReference[oaicite:19]index=19
