If you ever fought, this is a handy reference.
This DEV post shares a free world time API that works without accounts or keys, and it’s CORS-enabled.
What I liked:
- Offsets + dst flag included
- an /ip endpoint website for timezone auto-detect
- quick start examples

If you work on apps that need a trusted time source. Hope it helps.
