A free, global time service that you can use to synchronize to Google's atomic clocks.

What is NTP?

The Network Time Protocol (NTP) is used by hundreds of millions of computers and devices to synchronize their clocks over the Internet. If your computer sets its own clock, it likely uses NTP.

How is Google Public NTP different?

Google Public NTP serves leap-smeared time. We use this technology to smoothly handle leap seconds with no disruptive events.

We implemented Google Public NTP with our load balancers and our fleet of atomic clocks in data centers around the world.

We recommend that you don’t configure Google Public NTP together with non-leap-smearing NTP servers.
