I thought the ntp daemon also adjusted the clock rate to synchronise the system with the online ntp-servers.Chrony corrects the clock more quickly when it is far off, does a better job of keeping it correct when you are off-line, and corrects for hardware clock drift when restarting after the machine has been shut down. It is also trivially easy to configure: for most people it will "just work". It has no support for atomic clocks, GPS clocks, etc. and does not support some of the more esoteric features of the NTP protocol. Since it does not use exactly the same algorithms that Dr. Mills has analyzed it is possible (though unlikely) that a group of Chrony servers might be unstable under some circumstances (ones you will never experience). Ntpd supports numerous external clocks and can thus act as a stratum one server. It is the reference implementation of the protocol and so by definition supports all the features thereof. It's what national standards organizations such as NIST use.
Then for my laptop Chrony sounds more useful. Thanks for the info! Sjoerd -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments
