Ntp clock server.

Facebook NTP service is designed in four layers, or strata: Stratum 0 is a layer of satellites with extremely precise atomic clocks from a global navigation satellite system (GNSS), such as GPS, GLONASS, or Galileo. Stratum 1 is Facebook atomic clock synchronizing with a GNSS. Stratum 2 is a pool of NTP servers synchronizing to Stratum …3. The generic name time.nist.gov will continue to point to all of our servers on a round-robin basis, and users are encouraged to access the service using this name. Please address comments to: [email protected]. The global address time.nist.gov is resolved to all of the server addresses below in a round-robin sequence to equalize ... To use this specific pool zone, add the following to your ntp.conf file: server 3.ar.pool.ntp.org server 1.south-america.pool.ntp.org server 0.south-america.pool.ntp.org.

At the NRC main lab, the 3 stratum-1 servers are connected to Leitch 5300 Master Clock drivers which are synchronized to 3 separate cesium atomic frequency standards.An NTP server is a time source, while an NTP client is a system or device that tries to synchronize its clock with a server. Servers can be primary or secondary. A primary server gets UTC time signals from a highly precise source, such as an atomic clock or, more typically, a GPS signal source.

The term NTP applies to both the protocol and the client-server programs that run on computers. The NTP client initiates a time-request exchange with the NTP server. As a result of this exchange, the client is able to calculate the link delay and its local offset, and adjust its local clock to match the clock at the server’s computer.

See Time Synchronization. You might need to activate time synchronization using: $ sudo timedatectl set-ntp on. If you want to use chrony: If you require a one-shot sync use: $ chronyd -q.
