# chrony
|

|
||
Chrony is a pair of programs which are used to maintain the accuracy of the system clock on a computer.
|
||
The two programs are called chronyd and chronyc.
|
||
Chronyd is a daemon which runs in background on the system.
|
||
It obtains measurements via the network of the system clock’s offset relative to time servers on other systems and adjusts the system time accordingly.
|
||
For isolated systems, the user can periodically enter the correct time by hand (using Chronyc).
|
||
In either case, Chronyd determines the rate at which the computer gains or loses time, and compensates for this.
|
||
Chronyd implements the NTP protocol and can act as either a client or a server.
|
||
|
||
Chronyc provides a user interface to Chronyd for monitoring its performance and configuring various settings.
|
||
It can do so while running on the same computer as the Chronyd instance it is controlling or a different computer.
