Use it in code
const res = await fetch("https://www.datetimes.today/api/public/time/Europe/London");
const { datetime, utc_offset, dst_active, next_transition } = await res.json();
console.log(datetime, utc_offset, dst_active, next_transition);Unknown zones return 404 with {"error":"unknown_timezone"}. Responses are cached 30 seconds at the edge, so hammering it is cheap — but please cache on your side too.
