Sharing a handy GitHub repo here for a public world time JSON API.
What it does: timezone-aware responses, daylight saving logic, offset info, plus an IP-to-timezone endpoint for auto-detecting the user’s local time. No API key needed, and it’s browser-friendly via CORS for frontend fetch. :contentReference[oaicite:19]index=19

Good for: scheduling, countdowns, and avoiding unreliable client clocks. :contentReference[oaicite:21]index=21
