Cloudflare Time is a free NTP service served from Cloudflare’s global anycast network, so queries are answered by the closest point of presence.
Cloudflare’s time service supports NTS (Network Time Security), which cryptographically authenticates NTP responses and protects against man-in-the-middle attacks. It was one of the first production NTS deployments on the Internet.
