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.
