chrony is an implementation of the NTP (Network Time Protocol). It has some advantages against the standard ntpd (= Network Time Protocol daemon).
- chrony can synchronize to the timeserver much faster than NTP. This is good for laptops or desktops that don’t run constantly.
- It can compensate for fluctuating clock frequencies, such as when a host hibernates or enters sleep mode, or when the clock speed varies due to frequency stepping that slows clock speeds when loads are low.
- It handles intermittent network connections and bandwidth saturation.
- It adjusts for network delays and latency.
- After the initial time sync, chrony never steps the clock. This ensures stable and consistent time intervals for system services and applications.
- chrony can work even without a network connection. In this case, the local host or server can be updated manually.
