If timezones have ever made you suffer, this is a handy reference.
Here’s a DEV write-up on a public world time API that needs no sign-ups or keys, and it’s CORS-enabled.
What I liked:
- Offsets + dst flag included
- Geo-IP endpoint Geo-IP timezone detection API to detect the user timezone
- quick start examples
