If timezones have more info ever made you suffer, this might help.
This article explains a public world time API that needs no accounts or keys, and it’s frontend-friendly via CORS.
What I liked:
- Offsets + dst flag included
- Geo-IP endpoint to detect the user timezone
- Simple GET requests

Useful for frontend countdowns. Hope it helps.
