System Clock Synchronization Client and Server
Chrony is an implementation of the Network Time Protocol (NTP). It can
synchronize the system clock with NTP servers, reference clocks (e.g. a
GPS receiver), and manual input using wristwatch and keyboard. It can
also operate as an NTPv4 (RFC 5905) server and peer to provide a time
service to other computers in the network.
Chrony consists of two programs: chronyd and chronyc.
Chronyd is a daemon which runs in the background on the system. It
obtains measurements of the system clock’s offset relative to time
servers on other systems via the network 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 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.

Revision 115 (latest revision is 155)
Reinhard Max (rmax)
committed
(revision 115)
- Update to 4.4:
* Add support for AES-GCM-SIV with Nettle >= 3.9 to shorten NTS
cookies to avoid some length-specific blocking of NTP on
Internet.
* Add support for multiple refclocks using extpps option on one
PHC.
* Add maxpoll option to hwtimestamp directive to improve PHC
tracking with low packet rates
* Add hwtstimeout directive to configure timeout for late
timestamps.
* Handle late hardware transmit timestamps of NTP requests on
all sockets.
* Handle mismatched 32/64-bit time_t in SOCK refclock samples
* Improve source replacement
* Log important changes made by command requests (chronyc)
* Refresh address of NTP sources periodically
* Set DSCP for IPv6 packets
* Shorten NTS-KE retry interval when network is down
* Update seccomp filter for musl
* Warn if loading keys from file with unexpected permissions
* Warn if source selection fails or falseticker is detected
* Add selectopts command to modify source-specific selection
options.
* Add timestamp sources to serverstats report and make its fields
64-bit.
* Add -e option to chronyc to indicate end of response
- Update clknetsim to snapshot ef2a7a9.
