Time synchronization

Reliable, securely synchronized time is a building block for the Internet and other critical infrastructure.
Project Pendulum is the home for our time synchronization projects. It provides modern implementations of the Network Time Protocol and Precision Time Protocol and creates open services that boost secure time synchronization.
What We've Done
Our Network Time Protocol implementation, ntpd-rs, is stable. It is packaged for, for example, Fedora, Debian and Ubuntu and deployed at Let's Encrypt.

Enabling pools in NTS
We previously talked about how secure time is required for a safe internet. We mentioned how we want to increase the adoption of NTS, the secure time synchronization standard built on top of NTP. For this, we proposed to develop a public NTS pool. In this article, we expand on what pooling is, and what is required to enable an NTS pool.

ISPCS paper: Estimating noise for clock-synchronizing Kalman filters
Our Statime project now provides strong synchronization performance and accurate synchronization error estimates. David's paper, soon to be published by the IEEE, describes our Kalman-based approach.

More Memory Safety for Let’s Encrypt: Deploying ntpd-rs
When we look at the general security posture of Let’s Encrypt, one of the things that worries us most is how much of the operating system and network infrastructure is written in unsafe languages like C and C++.

A safe Internet requires secure time
The internet has a hole at the bottom of its trust stack, and we need to do something about it. In particular, the internet needs secure time synchronization to fortify the security of our digital world.
