Using Cloudflare’s Time Service

Network Time Protocol (NTP) is an Internet protocol designed to synchronize time between computer systems communicating over unreliable and variable-latency network paths. Cloudflare offers its version of NTP for free so you can use our global Anycast network to synchronize time from our closest server.

To use our NTP server, change the time configuration in your device to point to time.cloudflare.com.
