WebChrony Is an NTP implementation containing two programs: the chronyd daemon and a command line interface called chronyc. Chrony has some features that in many cases are simply irreplaceable: Chrony can synchronize with the time server much faster than the old ntpd service. This is good for laptops or desktop computers that do not work all the time. WebJul 11, 2024 · The precision of a clock describes how consistent its time and frequency are relative to a reference time source, when measured repeatedly. The distinction between precision and accuracy is subtle but important. ... Besides that, there are many other 3rd party implementations such as Chrony, Ntimed, FSMLabs TimeKeeper, etc.
