Versatile implementation of the Network Time Protocol (NTP)

历史

项目历史与用法

chrony is a long-running GPLv2 implementation of NTP with a daemon, chronyd, and a control CLI, chronyc, designed for accurate clock synchronization under difficult real-world network and hardware conditions.

项目历史

The official site says chrony was originally written by Richard Curnow and is currently maintained by Miroslav Lichvar. Its release archive reaches back to the 1.x series, and the current source repository is hosted on GitLab.

chrony was designed to work well with intermittent network access, congested networks, temperature-sensitive clocks, systems that suspend or do not run continuously, and virtual machines.

采用历史

The official download page says most Linux distributions and BSD systems provide a chrony package and recommends using those packages because they are integrated with service files and networking scripts. The supplied package facts list broad packaging across apk, Homebrew, Debian, dnf, MacPorts, Nix, pacman, Ubuntu, and zypper.

使用方式

chronyd runs as the time-synchronization daemon, while chronyc monitors and changes daemon parameters. A common configuration points chrony.conf at NTP servers or pools, stores drift, allows initial clock stepping, and may use /etc/chrony.keys for symmetric-key authentication.

为什么软件包爱好者会关心

chrony is a classic system package: small, daemon-oriented, security-sensitive, and heavily integrated with init systems and distribution defaults. It is also one of the packages where downstream packaging choices matter because service users, default config paths, network-online behavior, and crypto support affect the correctness of the system clock.

时间线

  • 2000s: 1.x tarballs available in the official release archive.
  • 2020: 4.0 series began after the 3.x line.
  • 2024: 4.6 added newer NTP and PTP-related configuration options.
  • 2025: 4.7 added systemd Type=notify support and other daemon improvements.
  • 2025: 4.8 released as the latest stable release on the official download page.

Related projects

  • Related projects and alternatives include ntp, ntpsec, OpenNTPD, systemd-timesyncd, pool.ntp.org, GPS/PPS reference-clock tooling, and Network Time Security implementations.
